17. Timer A
MR1 (External trigger select bit) (b3)
This bit is enabled when the MR2 bit is 1, and bits TAiTGH to TAiTGL in the ONSF register or TRGSR
register are set to 00b (TAiIN pin input).
TCK1 and TCK0 (Count source select bit) (b7-b6)
These bits are enabled when the TCS3 bit or TCS7 bit in registers TACS0 to TACS2 is set to 0 (TCK0
to TCK1 enabled).
Set the PCLK0 bit in the PCLKR register to select f1TIMAB or f2TIMAB.
