[Precautions for D-A converter]
1. Pin DAi is multiplexed with an analog input pin, external interrupt input pin, and trigger input pin in the
pulse output port mode. When any of the D-Ai output enable bits is set to “1” (output enabled), the
corresponding pin is used as pin DAi, not as any other multiplexed input/output pin (including a programmable
I/O port pin).
2. When not using the D-A converter, be sure to do as follows:
• Clear the D-A (i = 0, 1) output enable bit (bits 0, 1 at address 9616) to “0.”
i
• Clear the contents of D-A register i (addresses 9816, 9916) to “0016.”
