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 41).
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
41.
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
41.

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
10.4.2.12.
Bit 1 = REN: Retrigger mode.
0: Enable retriggerable mode
1: Disable retriggerable mode
Bit 0 = CO: Continous/One shot mode.
