Initial Compare Output Values (Compare Mode) - Texas Instruments CC253x User Manual

Assuming that channel 1 and channel 2 are used to drive the outputs using timer up-and-down mode and
the channels use output compare modes 4 and 5, respectively, then the timer period (in Timer 1 clock
periods) is:
t = T1CC0 × 2
P
and the dead time, that is, the time when both outputs are low, (in Timer 1 clock periods) is given by:
t = T1CC1 – T1CC2
D
A compare output pin is initialized to the value listed in
• a value is written to T1CNTL (all Timer 1 channels)
• 0x7 is written to T1CCTLn.CMP (channel n)
Compare Mode (
Set output on compare-up, clear on compare down in up-and-down mode (011)
In other modes than up-and-down mode, set output on compare, clear on 0
Clear output on compare-up, set on compare down in up-and-down mode (100)
In other modes than up-and-down mode, clear output on compare, set on 0
Clear when equal T1CC0, set when equal
