UART serial data input.
UART IrDA data input when IrDA mode is enabled (see
above).
Active-low modem data-carrier-detect input.
Active-low modem data- terminal-ready output. If automated
DTR# flow control is enabled, the DTR# pin is asserted and
de-asserted if the receiver FIFO reaches or falls below the
programmed thresholds, respectively.
In RS485 half - duplex mode, the DTR# pin may be
programmed to reflect the state of the transmitter empty bit to
automatically control the direction of the RS485 transceiver
buffer (see register ACR[4:3]).
Transmitter 1x clock (baud rate generator output). For
isochronous applications, the 1x (or Nx) transmitter clock may
be asserted on the DTR# pin (see register CKS[5:4]).
Active–low modem request - to-send output.
RTS# flow control is enabled, the RTS# pin is de-asserted
and reasserted whenever the receiver FIFO reaches or falls
below the programmed thresholds, respectively.
Active-low modem clear-to-send input. If automated CTS#
flow control is enabl e d, upon de-assertion of the CTS# pin,
the transmitter will complete the current character and enter
the idle mode until the CTS# pin is reasserted. Note: flow
control characters are transmitted regardless of the state of
the CTS# pin.
Active-low modem data-set - ready input. If automated DSR#
flow control is enabled, upon de-assertion of the DSR# pin,
the transmitter will complete the current character and enter
the idle mode until the DSR# pin is reasserted. Note: flow
control characters are transmitted regardless of the state of
the DSR# pin
External receiver clock for isochronous applications. The
Rx_Clk_In is selected when register CKS[1:0] = ’01’
Active-low modem Ring-indicator input
External transmitter clock. This clock can be used by the
transmitter (and indirectly by the receiver) when register
CKS[6] = ‘1’.
Crystal oscillator output
Crystal oscillator input or external clock pin. Frequency
1.8MHz -> 60MHz

Normal Mode : Address bit 5
Local Bus Mode : Active-low local bus read enable
Normal Mode : Address bit 6
