FUNCTION
IC reset input, low active.
Main-clock oscillation input. Mask option to select main-clock type. When
Ring type is used. Connect to GND via the oscillation resistor.
Main-clock oscillation output. Mask option to select main-clock type.
General input port with pull-high selection. Each 2 input pins can be
programmed to generate interrupt request and used to release IC from
STOP mode.
General input/output pins. When used as output pin, it can be open–drain
or CMOS type and it can sink 8mA for high-current applications. When
used as input pin, there may have a pull-high option and generate
interrupt request to release IC from STOP mode.
When BP0[7] is used as output pin, it can be the IR transmission carrier
for IR applications.
General input/output pins. When used as output pin, it can be open–drain
or CMOS type. When used as input pin, there may have a pull-high option
and generate interrupt request to release IC from STOP mode.
When serial interface is enabled, BP1[6:4] are used as serial interface
pins.
General input/output pins. When used as output pin, it can be open–drain
or CMOS type. When used as input pin, there may have a pull-high option
and generate interrupt request to release IC from STOP mode.
General output pins. The pins of OP0 are Inverter-type output.
Current type DAC speaker output.
Test input, internally pulled low. Do not connect during normal operation.
Positive power supply for P and peripherals.
Negative power supply for P and peripherals.
Positive power supply for oscillation.
Negative power supply for oscillation.
2 In order to get a stable oscillating frequency, W567B030~B260 provides these pins for power supply.
