88 / 92 page  ZIOL2xxx Datasheet © 2016 Integrated Device Technology, Inc. 88 April 26, 2016 Appendix B ZIOL2xxx Configuration Techniques The ZIOL2xxx allow various configurations to work optimal in several applications. Basically the ZIOL2xxx can be configured to work in applications with or without µC. Figure 10.6 Configuration Checker Report of the ZIOL2xxx Application Kit (Example) Application Kit - ZIO2401 (c) ZMDI - V2.1, built 28.04.2011 10:06:42 (UTC) ZIOL2211 Rev.B - Configuration Check on: 29-Apr-2011 09:52:11 Number of Warnings: 1 Number of Errors: 1 IO-Link Wake-up (WURQ) Detection WURQ detection is assigned to channel: COM WURQ detection method: - WURQ detection on current (overload) - WURQ detection on antivalent levels COM Channel Transmitter Current Limit: 50 ... 65 mA High-Side: enabled Low-Side: enabled Slew Rate Control: 10 V/µs 150k-Resistor usage: OFF Signal inverter: OFF COM Channel Receiver Receiver logic input levels: absolute (IO-Link conform) Analog filter: OFF Digital filter: OFF Signal inverter: OFF Sink Mode: OFF Sink strength: 2 ... 3 mA COM channel protection settings Assert time (persist overload during this period will lead to locked driver): 0 ms >>> Warning: zero assert time can lead to immediately locked driver! Lock time (period after lock will be removed automatically): 100 ms High-Side: Overload and wake-up detection: enabled Driver lock due to HS overload exceeds assert time: enabled Low-Side: Overload and wake-up detection: enabled Driver lock due to LS overload exceeds assert time: enabled AUX Channel Transmitter Current Limit: 50 ... 65 mA High-Side: enabled Low-Side: enabled Slew Rate Control: 10 V/µs 150k-Resistor usage: OFF Signal inverter: OFF AUX Channel Receiver Receiver logic input levels: absolute (IO-Link conform) Analog filter: OFF Digital filter: OFF Signal inverter: OFF Sink Mode: OFF Sink strength: 2 ... 3 mA AUX channel protection settings Assert time (persist overload during this period will lead to locked driver): 50 ms Lock time (period after lock will be removed automatically): 0 ms High-Side: Overload and wake-up detection: enabled Driver lock due to HS overload exceeds assert time: enabled Low-Side: Overload and wake-up detection: enabled Driver lock due to LS overload exceeds assert time: enabled Over-temperature protection settings Over-temperature protection: enabled Channel locking: enabled Max. allowed die temperature: >>> Error: Multiple or no temperature level selected Assert time (persist over-temperature during this period will lock both drivers): 100 ms Lock time (period after lock will be removed automatically): 200 ms Power-Fail protection settings Under-Voltage protection (channel locking): disabled Line-Fail protection (channel locking): disabled Master/Device mode settings IC Mode: Device Mode Pin Configuration Settings WURQ_L pin (IO-Link wake-up signaling): push/pull INT_L pin (for exception signaling settings refer below): push/pull DC_RDY pin: delay 50 ms Exception Signaling Interrupt (INT_L) will be active if one of the following exceptions occurred: - Both channels are locked due to Power-Fail - Wake-up has been detected (WURQ) - The EEPROM is corrupt (valid-latch error) - There is a general EEPROM error - There is a 2-bit EEPROM error - The AUX channel is locked due to over-current - The COM channel is locked due to over-current - Both channels are locked due to over- temperature IRQ_Port (INT_L pin) follows: state signals Configuration Register Summary ConfigReg[0] = 0xFF ConfigReg[1] = 0x03 ConfigReg[2] = 0x00 ConfigReg[3] = 0x03 ConfigReg[4] = 0x00 ConfigReg[5] = 0xC8 ConfigReg[6] = 0x64 ConfigReg[7] = 0x06 ConfigReg[8] = 0x64 ConfigReg[9] = 0x0F ConfigReg[10] = 0x00 ConfigReg[11] = 0x3F ConfigReg[12] = 0x32 ConfigReg[13] = 0x3F ConfigReg[14] = 0xEB ConfigReg[15] = 0x00 Summary Data Path Configuration Recommendations as regards the optimal configuration of the IC are provided by IDT in application notes and associated XML-Data-Files. Those XML-Data can be loaded into the IC using the also by IDT provided ZIOL2xxx application kits. Moreover, the user interface program of the ZIOL2xxx application kit provides a “configuration checker tool” which allows reviewing the IC configuration in a plain text report and which provides error and warning messages in case of wrong or critical IC configurations as illustrated in Figure 10.6. |
