Peripherals : I/O ports
13.4.8 32.768 kHz XOSC input
Ports P2_3 and P2_4 are used to connect an
external 32.768 kHz crystal. These port pins
will be used by the 32.768 kHz crystal
oscillator when CLKCON.OSC32K is low,
13.4.9 Radio Test Output Signals
For debug purposes and to some degree
CC2420 pin compability, the RFSTATUS.SFD,
RFSTATUS.FIFO, RFSTATUS.FIFOP and
RFSTATUS.CCA bits can be output onto P1.7 –
P1.4 I/O pins to monitor the status of these
signals. These test output signals are selected
by the IOCFG0, IOCFG1 and IOCFG2
registers.
The debug signals are output to the following
I/O pins:
regardless of register settings. The port pins
will be set in analog mode when
CLKCON.OSC32K is low.
• P1.4 – FIFO
• P1.5 – FIFOP
• P1.6 – SFD
• P1.7 – CCA
Configuring this mode has precedence over
other settings in the IOC, and these pins will
be assigned the above signals and forced to
be outputs.
13.4.10 I/O registers
The registers for the I/O ports are described in
this section. The registers are:
• P0 Port 0
• P1 Port 1
• P2 Port 2
• PERCFG Peripheral control register
• ADCCFG ADC input configuration register
• P0SEL Port 0 function select register
• P1SEL Port 1 function select register
• P2SEL Port 2 function select register
• P0DIR Port 0 direction register
P0 (0x80) – Port 0
• P1DIR Port 1 direction register
• P2DIR Port 2 direction register
• P0INP Port 0 input mode register
• P1INP Port 1 input mode register
• P2INP Port 2 input mode register
• P0IFG Port 0 interrupt status flag register
• P1IFG Port 1 interrupt status flag register
• P2IFG Port 2 interrupt status flag register
• PICTL Interrupt mask and edge register
• P1IEN Port 1 interrupt mask register
