Serial receive data. Serial input data for receiver. Timer 2 input/output.
Serial transmit data. Serial output data from transmitter.
Serial control 2.Transmitter frame sync only in asynchronous mode,
transmitter and receiver frame sync in synchronous mode.
Serial control 1. Receive frame sync in asynchronous mode, output
from transmitter 2 or serial flag 1 in synchronous mode.
Test data output (input/output). Debug request input and acknowledge output.
Non-maskable interrupt/ PINIT. Used to enable the PLL during RESET
Serial receive data. Serial input data for receiver.
IO power supply.
IO ground.
Serial Transmit Data. Serial output data from transmitter.
ESSI1 serial control 0. Receive clock in asynchronous mode, output from
transmitter or serial flag in synchronous mode.
I
Serial control 0. Receive clock in asynchronous mode, output from transmitter
1 or serial flag 0 in synchronous mode.
SCI receive data. Receives byte-oriented serial data.
SCI read enable. Transmits serial data from SCI transmit shift register.
SCI serial clock. Input or output clock from which data is transferred in
synchronous mode and from which the transmit and/or receive baud rate is
derived in asynchronous mode.
Serial clock. Serial bit clock for transmitter only in asynchronous mode, serial
bit clock for both receiver and transmitter in synchronous mode.
Timer 1 input/output.
Serial clock. Serial bit clock for transmitter only in asynchronous mode, serial
bit clock for both receiver and transmitter in synchronous mode.
System reset. A low level applied to RESET_N input initializes the IC.
SCAN enable. When active with TESTEN also active, controls the shifting of
the internal scan chains.
Test enable. When active, puts the chip into test mode and muxes the XTI
clock to all flip-flops. When SCANEN is also active, the scan chain shifting is
enabled.
Core ground.
Core power supply.
Timer 0 input/output.
Analog substrate isolation.
