8 – 6

* 3A I/F : 3 V analog circuit input/output pin.

1.5 I/F : 1.5 V digital input/output pin.
3 I/F : 3 V digital input/output pin.

Note: The servo output pins (FOO, TRO, FMO, and DMO) become undefined or GND level under the following conditions:

• /RST pin = Low
• Crystal oscillation stopped according to the instructions by the Stop crystal oscillation command.
• Power supply for CD is OFF.
• SRAMSTB pin = High
To prevent the undefined pin states from affecting the servo circuitry or any other mechanical blocks in the system,
appropriate measures should be taken, such as using a driver IC supporting a standby feature to place the system in
standby mode while either of the above conditions is satisfied.
