ST90158 - MULTIFUNCTION TIMER (MFT)

MULTIFUNCTION TIMER (Cont’d)

TIMER MODE REGISTER (TMR)

R249 - Read/Write

Reset value: 0000 0000 (00h)

Bit 7 = OE1:

Output 1 enable.

0: Disable the Output 1 (TxOUTB pin) and force it

high.

1: Enable the Output 1 (TxOUTB pin)

The relevant I/O bit must also be set to Alternate

Function

Bit 6 = OE0:

Output 0 enable.

0: Disable the Output 0 (TxOUTA pin) and force it

high

1: Enable the Output 0 (TxOUTA pin).

The relevant I/O bit must also be set to Alternate

Function

Bit 5 = BM:

Bivalue mode.

This bit works together with the RM1 and RM0 bits

to select the timer operating mode (see Table 24).

0: Disable bivalue mode

1: Enable bivalue mode

Bit 4 = RM1:

REG1R mode.

This bit works together with the BM and RM0 bits

to select the timer operating mode. Refer to Table

24.

Note: This bit has no effect when the Bivalue

Mode is enabled (BM=1).

Bit 3 = RM0:

REG0R mode.

This bit works together with the BM and RM1 bits

to select the timer operating mode. Refer to Table

24.

Table 24. Timer Operating Modes

Bit 2 = ECK

Timer clock control.

0: The prescaler clock source is selected depend-

ing on the IN0 - IN3 bits in the T_ICR register

1: Enter Parallel mode (for Timer 1 and Timer 3

only, no effect for Timer 0 and 2). See Section

9.2.2.12.

Bit 1 = REN:

Retrigger mode.

0: Enable retriggerable mode

1: Disable retriggerable mode

Bit 0 = CO:

Continous/One shot mode.

0: Continuous mode (with autoreload on End of

Count condition)

1: One shot mode
