26.2.9 Period/Capture Register n (PERCAPx)
The PERCAPx registers are word-wide read/write registers. There are a total of four registers called
PERCAP1 through PERCAP4, one for each timer subsystem. The registers hold the period compare value
in PWM mode of the counter value at the time the last associated capture event occurred. In PWM mode
the register is double buffered. If a new period compare value is written while the counter is running, the
write will not take effect until counter value matches the previous period compare value or until the counter
is stopped. Reading may take place at any time and will return the most recent value which was written.
The PERCAPx registers are cleared at reset.

26.2.10 Duty Cycle/Capture Register n (DTYCAPx)
The Duty Cycle/Capture (DTYCAPx) registers are word-wide read/write registers. There are a total of four
registers called DTYCAP1 through DTYCAP4, one for each timer subsystem. The registers hold the
period compare value in PWM mode or the counter value at the time the last associated capture event
occurred. In PWM mode, the register is double buffered. If a new duty cycle compare value is written while
the counter is running, the write will not take effect until the counter value matches the previous period
compare value or until the counter is stopped. The update takes effect on period boundaries only. Reading
may take place at any time and will return the most recent value which was written. The DTYCAPx
registers are cleared at reset.
