* 3A I/F : : 3 V analog circuit input/output pin.
1.5 I/F : 1.5Vdigital 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:
x /RST pin Low
x Crystal oscillation stopped according to the instructions by the Stop crystal oscillation command
x Power supply for CD is OFF.
x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.
