Type Symbol I/O Name and Function
Power VCC Input Power supply: For connection to the power supply.
All VCC pins should be connected to the system power
supply.
PVCC1,
PVCC2
Input Port power supply pin. Connect all pins to the same
power supply.
VSS Input Ground: For connection to ground
(0 V). All VSS pins should be connected to the system
power supply (0 V).
Clock PLLVCC Input PLL power supply: Power supply for on-chip PLL
oscillator.
PLLVSS Input PLL ground: Ground for on-chip PLL oscillator.
PLLCAP Input PLL capacitance: External capacitance pin for on-chip
PLL oscillator.
XTAL Input Connects to a crystal oscillator.
See section 23A, Clock Pulse Generator (H8S/2633,
H8S/2632, H8S/2631, H8S/2633F), for typical
connection diagrams for a crystal oscillator and external
clock input.
EXTAL Input Connects to a crystal oscillator.
The EXTAL pin can also input an external clock.
See section 23A, Clock Pulse Generator (H8S/2633,
H8S/2632, H8S/2631, H8S/2633F), for typical
connection diagrams for a crystal oscillator and external
clock input.
OSC1 Input Subclock: Connects to a 32.768 kHz crystal oscillator.
See section 23A, Clock Pulse Generator (H8S/2633,
H8S/2632, H8S/2631, H8S/2633F), for examples of
connections to a crystal oscillator.
OSC2 Input Subclock: Connects to a 32.768 kHz crystal oscillator.
See section 23A, Clock Pulse Generator (H8S/2633,
H8S/2632, H8S/2631, H8S/2633F), for examples of
connections to a crystal oscillator.
