SIGNAL
DESCRIPTIONS
2
PRELIMINARY
PG1/RXD—UART RECEIVE DATA, PORT G 1
This pin is the receiver serial input. While in normal operation, NRZ data is expected. While
in infrared mode, a narrow pulse is expected for each “zero” bit received. An external IR
transceiver RXD signal may be connected directly to this pin. RS-232 applications need an
external RS-232 line-receiver to convert voltage levels. By default after reset, this pin
becomes general-purpose input, PG1.
PM0/CTS—CLEAR TO SEND, PORT M 0
This input controls the transmitter. Normally, the transmitter waits until this signal is active
(low) before a character is transmitted. If the IGNORE CTS bit is set, the transmitter sends
a character whenever a character is ready to transmit. This pin can then be used as a
general-purpose input whose status is read in the CTS STATUS bit. This pin can post an
interrupt on any transition of CTS, if enabled. By default after reset, this pin becomes CTS.
PM1/RTS—REQUEST TO SEND, PORT M 1
This pin serves two purposes. Normally, the receiver indicates that it is ready to receive data
by asserting this pin (low). This pin would be connected to the far-end transmitter’s CTS pin.
When the receiver detects a pending overrun, it negates this pin. For other applications, this
pin can be a general-purpose output controlled by the bit in the receiver register. When it is
programmed as parallel I/O, it becomes PM1. By default after reset, this pin becomes
general-purpose input, PM1.
PM7/GPIO—UART GENERAL PURPOSE I/O, PORT M 7
This pin provides several functions for the UART. It can provide a bit clock (input or output)
and a master clock for the baud generator (input). By default after reset, this pin becomes
UART GPIO.
2.1.13 Timer Pins
PG6/TIN1—TIMER 1 INPUT, PORT G 6
This bidirectional pin can be programmed as a clock input that causes events to occur in
timer/counter channel 1; either causing a clock to the event counter or providing a trigger to
the timer value capture logic. By default after reset, this pin becomes general-purpose input,
PG6.
PG4/TIN2—TIMER 2 INPUT, PORT G 4
This bidirectional signal can be programmed as a clock input that causes events to occur in
timer/counter channel 2; either causing a clock to the event counter or providing a trigger to
the timer value capture logic. By default after reset, this pin becomes general-purpose input,
PG4.
PG5/TOUT1 —TIMER 1 OUTPUT, PORT G 5
This bidirectional signal can be programmed to toggle or generate a pulse of one system
clock duration when timer/counter channel 1 reaches a reference value. By default after
reset, this pin becomes general-purpose input, PG5.
