INTTM000 signal is not
generated even if value
is captured.
Interrupt signal
Set values of ES001 and
ES000
Position of edge to be
captured
01: Rising
11: Both edges
INTTM000 signal is
generated each time
value is captured.
00: Falling
11: Both edges
Interrupt signal
INTTM010 signal is
generated each time
value is captured.
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
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: See 6.3 (2) Capture/compare control register 00 (CRC00).
ES101, ES100, ES001, ES000: See 6.3 (4) Prescaler mode register 00 (PRM00).
