Interrupt signal
INTTM000 signal is not
generated even if value
is captured.
Interrupt signal
INTTM000 signal is
generated each time
value is captured.

Note 2
11: Both edges
Capture operation of
CR010
Interrupt signal
INTTM010 signal is
generated each time
value is captured.
Notes 1. 78K0/IB2 (30 pins) only
2. 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 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.
Remark CRC001: Refer to 7.3 (2) Capture/compare control register 00 (CRC00).
ES101, ES100, ES001, ES000: Refer to 7.3 (4) Prescaler mode register 00 (PRM00).
