AIN3 — ADC, input 3. This analog input is always connected to its pin.
EINT3 — External interrupt 3 input.
CAP0[0] — Capture input for Timer 0, channel 0.
Port 1 is a 32-bit bidirectional I/O port with individual direction controls for
each bit. The operation of port 1 pins depends upon the pin function selected
via the Pin Connect Block.
Pins 2 through 15 of port 1 are not available.
LOW-active Chip Select 0 signal.
(Bank 0 addresses range 0x8000 0000 to 0x80FF FFFF)
LOW-active Output Enable signal.
Trace Packet, bit 0. Standard I/O port with internal pull-up.
Trace Packet, bit 1. Standard I/O port with internal pull-up.
Trace Packet, bit 2. Standard I/O port with internal pull-up.
Trace Packet, bit 3. Standard I/O port with internal pull-up.
Trace Synchronization; standard I/O port with internal pull-up.
Note: LOW on this pin while RESET is LOW, enables pins P1[25:16] to
operate as Trace port after reset.
Pipeline Status, bit 0. Standard I/O port with internal pull-up.
Pipeline Status, bit 1. Standard I/O port with internal pull-up.
Pipeline Status, bit 2. Standard I/O port with internal pull-up.
Trace Clock. Standard I/O port with internal pull-up.
External Trigger Input. Standard I/O with internal pull-up.
Returned Test Clock output. Extra signal added to the JTAG port. Assists
debugger synchronization when processor frequency varies. Bidirectional pin
with internal pull-up.
Note: LOW on this pin while RESET is LOW, enables pins P1[31:26] to
operate as Debug port after reset.
Test Data out for JTAG interface.
Test Data in for JTAG interface.
Test Clock for JTAG interface. This clock must be slower than
clock (CCLK) for the JTAG interface to operate.
Test Mode Select for JTAG interface.
Test Reset for JTAG interface.
Port 2 is a 32-bit bidirectional I/O port with individual direction controls for
each bit. The operation of port 2 pins depends upon the pin function selected
via the Pin Connect Block.
