(a) Operation if TPnCCR0 register is set to 0000H
(b) Operation if TPnCCR0 register is set to FFFFH
Preliminary User’s Manual U17566EE1V2UM00
If the TPnCCR0 register is set to 0000H, the INTTPnCC0 signal is
generated each time the valid signal of the external event count signal has
been detected.
The 16-bit counter is always 0000H.
If the TPnCCR0 register is set to FFFFH, the 16-bit counter counts to
FFFFH each time the valid edge of the external event count signal has
been detected. The 16-bit counter is cleared to 0000H in synchronization
with the next count-up timing, and the INTTPnCC0 signal is generated. At
this time, the TPnOPT0.TPnOVF bit is not set.
