Description
P1.0 — General purpose digital input/output pin.
CS0 — LOW-active Chip Select 0 signal.
P1.1 — General purpose digital input/output pin.
OE — LOW-active Output Enable signal.
P1.16 — General purpose digital input/output pin.
TRACEPKT0 — Trace Packet, bit 0. Standard I/O port with internal pull-up.
P1.17 — General purpose digital input/output pin.
TRACEPKT1 — Trace Packet, bit 1. Standard I/O port with internal pull-up.
P1.18 — General purpose digital input/output pin.
TRACEPKT2 — Trace Packet, bit 2. Standard I/O port with internal pull-up.

P1.23 — General purpose digital input/output pin.
PIPESTAT2 — Pipeline Status, bit 2. Standard I/O port with internal pull-up.
P1.24 — General purpose digital input/output pin.
TRACECLK — Trace Clock. Standard I/O port with internal pull-up.
P1.25 — General purpose digital input/output pin.
EXTIN0 — External Trigger Input. Standard I/O with internal pull-up.
P1.26 — General purpose digital input/output pin.
RTCK — 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.
P1.27 — General purpose digital input/output pin.
TDO — Test Data out for JTAG interface.
P1.28 — General purpose digital input/output pin.
TDI — Test Data in for JTAG interface.
P1.29 — General purpose digital input/output pin.
TCK — Test Clock for JTAG interface.
P1.30 — General purpose digital input/output pin.
TMS — Test Mode Select for JTAG interface.
(Bank 0 addresses range 0x8000 0000 to 0x80FF FFFF)
