Timer Interface Module A (TIMA)
11.10.5 TIMA Channel Registers
Technical Data
192
Address:
Address:
These read/write registers contain the captured TIMA counter value of
the input capture function or the output compare value of the output
compare function. The state of the TIMA channel registers after reset is
unknown.
In input capture mode (MSxB:MSxA = 0:0), reading the high byte of the
TIMA channel x registers (TACHxH) inhibits input captures until the low
byte (TACHxL) is read.
In output compare mode (MSxB:MSxA ≠ 0:0), writing to the high byte of
the TIMA channel x registers (TACHxH) inhibits output compares until
the low byte (TACHxL) is written.
