TAiMR Register in Event Counter Mode (when not using two-phase pulse signal
processing)
Note 1: During event counter mode, the count source can be selected using the ONSF and TRGSR
registers.
Note 2: TA0OUT pin is N-channel open drain output.
Note 3: Effective when the TAiGH and TAiGL bits of ONSF or TRGSR register are ‘002’ (TAiIN pin input).
Note 4: Count down when input on TAiOUT pin is low or count up when input on that pin is high. The port
direction bit for TAiOUT pin must be set to “0” (= input mode).
