Function
VCC2 (P85
to P87)
P86 and P87 that when selected in a program, both can function as I/O
pins for sub clock oscillation circuit. In that case, connect crystal
resonator between P86 (XCOUT pin) and P87 (XCIN pin).
P85 is an input-only port shared with NMI. NMI interrupt is generated
when input on this pin changes state from high to low.
NMI function cannot be disabled in a program. Pull-up resistor cannot
be set for this pin.
VCC2
This is an 8-bit I/O port equivalent to P0. Pins in this port also function
as SI/O3 and SI/O4 of I/O pins, Timer B0 to B4 input pins, A/D
converter input pins, A/D trigger input pins, or remote control input pins
as selected by program.
Analog power supply pin. Apply the same potential as VCC2 to the
VDD2 pin. Apply 0 V to the VSS2 pin.
VCC2
This pin inputs the external composite video signal. Data-acquisition
slices this signal internally by setting.
VCC2
This pin inputs the external composite video signal. Sync.-separate
circuit devides this signal internally.
VCC2
This pin selects the oscillation circuit. XIN-XOUT circuit is selected when
this pin is "L"; XCIN-XCOUT circuit is selected when this pin is "H".
VDD2
This is a filter output pin 2 (for VPS).
VDD2
This is a filter output pin 3 (for PDC).
VCC2
Normally, please input "L" level. When VCC1 power supply is off, please
input "H" level.
VCC2
Connect it to the VSS.In the mask ROM version, connect this pin to the
VSS or the VCC2.
VCC2
This is a test pin. Connect a capacitor.
