8.4 15-bit interval timer operation
8.4.1 15-bit interval timer operation timing
Runs as a 15-bit interval timer for repeated interrupt requests (INTITs) at intervals set by ITCMP14 to
ITCMP0 bits. If you put the RINTE set to 1, the 15-bit counter starts counting.
When the 15-bit count value and the ITCMP14~ITCMP0 config value are the same, clear the 15-bit count
value to 0 and continue counting, while generating an interrupt request signal ( INTIT).
The basic operation of the 15-bit interval timer is shown in Figure 8-5.

=32.768kHz).)
start counting at the next rising edge of
counting clock after set RINTE bit from 0 to 1.
if RINTE bit clear from 1 to 0, then
asynchronizely clear 15 bit counter.
