Because some device packages lack a hardware RESET# input and a device that is in a continuous high performance read mode may not recognize any normal SPI command, a system hardware reset or software reset command may not be recognized by the device. It is recommended to use the MBR command after a system reset when the RESET# signal is not available or, before sending a software reset, to ensure the device is released from continuous high performance read mode. The MBR command sends Ones on SI or IO0 for 8 SCK cycles. IO1 to IO3 are “don’t care” during these cycles. Figure 86. Mode Bit Reset Command Sequence 9.10 Embedded Algorithm Performance Tables Notes: 1. Typical program and erase times assume the following conditions: 25°C, VCC = 3.0V; 10,000 cycles; checkerboard data pattern. 2. Under worst case conditions of 90°C; 100,000 cycles max. 3. Maximum value also applies to OTPP, PPBP, ASPP, PASSP, ABWR, and PNVDLR programming commands. 4. Maximum value also applies to the PPBE erase command. Table 50.
