Capture
Operation
Capture operation of
CR000
Capture operation of
CR010
Note The capture operation of CR010 is not affected by the setting of the CRC001 bit.
Caution To capture the count value of the TM00 register to the CR000 register by using the phase
Remark CRC001: See 6.3 (2) Capture/compare control register 00 (CRC00).
External Input
Signal
reverse to that input to the TI000 pin, the interrupt request signal (INTTM000) is not generated
after the value has been captured. If the valid edge is detected on the TI010 pin during this
operation, the capture operation is not performed but the INTTM000 signal is generated as an
external interrupt signal. To not use the external interrupt, mask the INTTM000 signal.
ES101, ES100, ES001, ES000: See 6.3 (4) Prescaler mode register 00 (PRM00).
