Pinout and Signal Description
PS0 / RXD0 — Port PS0 is a general purpose input or output pin. It can be configured as the
S I/O Pin 0
receive pin RXD of Serial Communication Interface 0 (SCI0).
PT[7:0] / IOC[7:0]
— Port T I/O Pins
[7:0]
PT7-PT0 are general purpose input or output pins. They can be
configured as input capture or output compare pins IOC7-IOC0 of the
Enhanced Capture Timer (ECT).

VDDX
Pseudo_open_drain communication pin for the
background debug mode. At the rising edge on RESET,

the state of this pin activates the BDM (when BKGD =
1). When instruction tagging is on, a 0 at the falling edge
of E tags the high half of the instruction word being read
into the instruction queue.
