9.3.1
DACNT is a 14-bit readable/writable up-counter. The input clock is selected by the clock select
bit (CKS) in DACR. DACNT functions as the time base for both PWMX (D/A) channels. When a
channel operates with 14-bit precision, it uses all DACNT bits. When a channel operates with 12-
bit precision, it uses the lower 12 bits and ignores the upper 2-bit counter. As DACNT is 16 bits,
data transfer between the CPU is performed through the temporary register (TEMP). For details,
see section 9.4, Bus Master Interface.

Register Select
DADRA and DACR, and DADRB and DACNT, are
located at the same addresses. The REGS bit specifies
which registers can be accessed.
0: DADRA and DADRB can be accessed
1: DACR and DACNT can be accessed
