(8) Buffer registers CM03, CM13 (BFCM03, BFCM13)
BFCMn3 is a 16-bit register that transfers data to the compare register at any timing. Transfer enable or
disable is controlled by the BFTE3 bit of the TMC0n register.
BFCMn3 can be read/written in 16-bit units.
Cautions 1. The set value of the BFCMn3 register is transferred to the CM0n3 register at the
following timing (n = 0, 1).
•
When TM0CEn bit of TMC0n register = 0: Transfer at the next operation timing after
writing to the BFCMn3 register
•
When TM0CEn bit of TMC0n register = 1: The value of the BFCMn3 register is
transferred to the CM0n3 register upon occurrence of INTTM0n. At this time, transfer
enable or disable is controlled by the BFTE3 bit of the timer control register (TMC0n).
2. Setting the BFCMn3 register to 0000H is prohibited.
