10.2.18 Buffer Registers (BFR)
The buffer registers (BFR) are 16-bit registers. The ATU has four buffer registers, one each for
channels 6 to 9.
Buffer Registers (BFR6 to BFR9)
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 are connected to the CPU via an internal 16-bit bus, and 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.
