CD function pins switched together
(Note) Symbols for the pins used above indicate the following pin functions:
* : CD processor-dedicated pin
M _{: Power supply pin}
3 : CD processor tri-state output pin
A : CD processor analog input/output pin
R : Reference input pin
M _{: Controller-dedicated pin}
(Note) When the CD is off, the power supply pins for the controller (MV_DD) and the power pins supply for the CD oscillator (XV_DD) are on and the CD processor-dedicated power
supply (indicated by an asterisk *) pins are off.
