Section 10 Advanced Timer Unit (ATU)
10.2.19 Duty Registers (DTR)
The duty registers (DTR) are 16-bit registers. The ATU has four duty registers, one each for
channels 6 to 9.

Duty Registers (DTR6 to DTR9)
The DTR registers are 16-bit readable/writable registers used for PWM duty storage.
The DTR value is constantly compared with the corresponding free-running counter (TCNT6 to
TCNT9) value, and when the two values match, the corresponding channel output pin (TO6 to
TO9) goes to 0 output.
The DTR registers are connected to the CPU via an internal 16-bit bus, and can only be accessed
by a word read or write.
The DTR registers are initialized to H'FFFF by a power-on reset, and in hardware standby mode
and software standby mode.
