Description
P2.0 secondary functions.
UART: Input pin for a synchronous communication receive data.
Synchronous: Input/output pin for serial port transmit/receive data.
P2.1 secondary functions.
UART: Input pin for a synchronous communication receive data.
Synchronous: Output pin for serial port synchronizing clock.
Secondary function of P2.2 input pin for external interrupt 0.
The interrupt can be triggered by the rising edge, falling edge, or both
edges of rising or falling.
Secondary function of P2.3 input pin for external interrupt 1.
The interrupt can be triggered by the rising edge, falling edge, or both
rising and falling edges. Also used as a gate signal input pin for gating
the counter of timer 0.
Secondary function of P3.4 input pin for external interrupt 2.
The interrupt can be triggered by the rising edge, falling edge, or both
rising and falling edges.
Secondary function of P2.0 input pin for hardware stop mode. If this pin goes
low while the HSTP bit in SBYCON is set to 1, the chip enters hard stop
mode. In hardware stop mode the clock stops and the CPU and on-chip
peripheral functions shut down to conserve power.
P3.5 secondary functions.
Shift register data output pin.
P3.6 secondary functions.
Shift register data output pin.
P3.7 secondary functions.
Shift register synchronizing clock input/output pin.
In master mode: clock output
In slave mode: clock input
Secondary function of P2.4: external clock input pin for timer 0.
Secondary function of P2.7: outputs a waveform with twice the cycle of
the overflow interval of timer 1.
Secondary function of P6.0 to P6.7: functions as analog input channel in
A/D conversion.
