10.2
Table 10.1 lists the PWM (D/A) module input and output pins.
Table 10.1 Pin Configuration
10.3
The PWM (D/A) module has the following registers. The PWM (D/A) registers are assigned to the
same addresses with other registers. The registers are selected by the IICE bit in the serial timer
control register (STCR). For details on STCR, see section 3.2.3, Serial Timer Control Register
(STCR).
Note: The same addresses are shared by DADRA and DACR, and by DADRB and DACNT.
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 PWM (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. Since DACNT consists of
16-bit data, DACNT transfers data to the CPU via the temporary register (TEMP). For details,
refer to section 10.4, Bus Master Interface.
