6 / 35 page Pin Functions No. 5190-6/35 Pin VDD VSS OSC1 OSC2 PA0 to PA3 PC0 to PC3 PD0 to PD3 Pin no. 1 1 1 1 4 4 4 I/O — — Input Output I/O I/O I/O Function Power supply • System clock oscillator Connect an external ceramic oscillator element to these pins • Leave OSC2 open if an external clock is supplied. • I/O port A0 to A3 Input in 4-bit units using the IP instruction Output in 4-bit units using the OP instruction Port bits can be tested in bit units using the BP and BNP instructions. Port bits can be set or cleared in bit units using the SPB and RPB instructions. • PA3 is used for standby control. • Applications must be designed so that no chattering (e.g. switch bounce) occurs on the PA3 pin during a HALT instruction execution cycle. • I/O port C0 to C3 The PC0 to PC3 pin functions are identical to those of the PA0 to 3 pins.* • High or low can be specified as the output at reset as an option. Note: These pins do not have a standby control function. • I/O port D0 to D3 The PD0 to PD3 pin functions and options are identical to those of the PC0 to PC3 pins. Options — (1) External clock (2) Two-pin ceramic oscillator (3) Divider circuit option 1. No divider circuit 2. Divide-by-three circuit 3. Divide-by-four circuit (1) Output open drain (2) Built-in pull-up resistor • Options (1) and (2) can be specified in bit units. (1) Output open drain (2) Built-in pull-up resistor (3) High-level output at reset (4) Low-level output at reset • Options (1) and (2) can be specified in bit units. • Option (3) and (4) are specified in 4-bit units. The same as PC0 to PC3. State at reset — — High-level output (i.e., the output n-channel transistor will be off.) • High-level output • Low-level output (Depending on the option specified.) The same as PC0 to PC3. Handling when unused — — Open drain output select the options, connect to VSS. The same as PA0 to PA3. The same as PA0 to PA3.
