Capture
Operation
Capture operation of
CR00n
Capture operation of
CR01n
Caution To capture the count value of the TM0n register to the CR00n register by using the phase
Remarks 1. CRC0n1: See 7.3 (2) Capture/compare control register 0n (CRC0n).
Note The capture operation of CR01n is not affected by the setting of the CRC0n1 bit.
External Input
Signal
reverse to that input to the TI00n pin, the interrupt request signal (INTTM00n) is not generated
after the value has been captured. If the valid edge is detected on the TI01n pin during this
operation, the capture operation is not performed but the INTTM00n signal is generated as an
external interrupt signal. To not use the external interrupt, mask the INTTM00n signal.
