10.3.1
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 two bits. DACNT cannot be accessed
in 8-bit units. DACNT should always be accessed in 16-bit units. For details, see section 10.4, Bus
Master Interface.

This bit is always read as 1 and cannot be modified.
Register Select
DADRA and DACR, and DADRB and DACNT, are
located at the same addresses. The REGS bit specifies
which registers can be accessed. When changing the
register to be accessed, set this bit in advance.
0: DADRA and DADRB can be accessed
1: DACR and DACNT can be accessed
