R249 - Read/Write
Register Page: 10
Reset value: 0000 0000 (00h)
Bit 7 = OE1: Output 1 enable.
0: Disable the Output 1 (TxOUTB pin) and force it
1: Enable the Output 1 (TxOUTB pin)
Bit 6 = OE0: Output 0 enable.
0: Disable the Output 0 (TxOUTA pin) and force it
1: Enable the Output 0 (TxOUTA pin).
Bit 5 = BM: Bivalu e mode .
This bit works together with the RM1 and RM0 bits
to select the timer operating mode (see
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
