Setting the MOD field in Timer Control Register n (TMnCON, n=0 - 5) to 2’b00 (ART)
configures timer channel n in auto-reload timer (ART) mode.
When Timer Counter n (TMnC, n=0 - 5) overflows, the timer channel automatically copies the
contents of Timer Register n (TMnR, n=0 - 5) into TMnC and generates an interrupt request
(FTMOVn, n=0 - 5).
Auto-reload timer (ART) mode does not change the level at Timer Output n pin (TMOUT[n],
n=0 - 5).
Setting the MOD field in Timer Control Register n (TMnCON, n=0 - 5) to 2’b01 (CMO)
configures timer channel n in compare out (CMO) mode.
When Timer Counter n (TMnC, n=0 - 5) matches Timer General-Purpose Register n (TMnGR,
n=0 - 5), the timer channel sets the output level for Timer Output n pin (TMOUT[n], n=0 - 5)
according to the IOLV field in Timer I/O Level Register n (TMnIOLV, n=0 - 5).
2’b00: A match between TMnC and TMnGR sets the output level to "0."
2’b01: A match between TMnC and TMnGR sets the output level to "1."
2’b10: A match between TMnC and TMnGR reverses the output level.
Counter overflow and matches both generate interrupt requests - FTMOVn and EVENTn (n=0
- 5), respectively.
