The CYLR registers can only be accessed by a word read or write.

The CYLR registers are initialized to H'FFFF by a power-on reset, and in hardware standby mode

and software standby mode.

For details of the CYLR, BFR, and DTR registers, see section 10.3.9, PWM Timer Function.

Buffer Registers (BFR)

The buffer registers (BFR) are 16-bit registers. The ATU-II has eight buffer registers, four each in

channels 6 and 7.

The BFR registers are 16-bit readable/writable registers that store the value to be transferred to the

duty register (DTR) in the event of a cycle register (CYLR) compare-match.

The BFR registers can only be accessed by a word read or write.

The BFR registers are initialized to H'FFFF by a power-on reset, and in hardware standby mode

and software standby mode.
