Table 1.3 (b) Pin Functions (H8S/2633R)
Type Symbol I/O Name and Function
Power VCL Output On-chip power supply stabilizer pin: The VCL pin need
not be connected to the power supply. Connect this pin
to VSS via a 0.1 μF capacitor (placed close to the
pins).
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 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 23B, Clock Pulse Generator (H8S/2633R,
H8S/2695), 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 23B, Clock Pulse Generator (H8S/2633R,
H8S/2695), 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 23B, Clock Pulse Generator (H8S/2633R,
H8S/2695), for examples of connections to a crystal
oscillator.
OSC2 Input Subclock: Connects to a 32.768 kHz crystal oscillator.
See section 23B, Clock Pulse Generator (H8S/2633R,
H8S/2695), for examples of connections to a crystal
oscillator.
φ Output System clock: Supplies the system clock to an external
device.
