12.6.1 Clock

357

Description amended

Eight serial clock pulses are output in the transfer of one

character, and when no transfer is performed, the clock is fixed

high. Only in reception, the serial clock is continued generating

until an overrun error is occurred or the RE bit is cleared to 0.

To execute reception in one-character units, select an external

clock as a clock source.

Compare Match Flag

This flag indicates whether or not the CMCNT and

CMCOR values have matched.

0: CMCNT and CMCOR values have not matched

1: CMCNT and CMCOR values have matched

[Clearing conditions]

•

Write 0 to CMF after reading 1 from it

•

When the DTC is activated by an CMI interrupt and

data is transferred with the DISEL bit in DTMR of

DTC = 0
