10.1.3 Pin Configuration
Table 10.1 lists the pins used by the PWM (D/A) module.
Table 10.1 PWM Timer Input and Output Pins
Name Abbr. I/O Function
PWM output pin 0 PWX0 Output PWM output, channel A
PWM output pin 1 PWX1 Output PWM output, channel B
10.1.4 Register Configuration
Table 10.2 lists the registers of the PWM (D/A) module.

Notes: 1. Lower 16 bits of the address.
2. Registers in the 14-bit PWM timer are assigned to the same addresses as the other
registers. In this case, register selection is performed by the IICE bit in the serial timer
control register (STCR), and also the same addresses are shared by DADRAH and
DACR, and by DADRB and DACNT. Switching is performed by the REGS bit in DACNT
or DADRB.
