Pin 142: TXCMD/LA21
The TXCMD/LA21 pin may be configured to operate as
input or output and may be configured to drive a trans-
ceiver control reference signal using one of two timing
sources plus input from the TXCMD bit of TIR11
(TIR11[0]). Note that some functionality is only available
in PCMCIA mode.
Pin functionality is programmed according to the
following table.

/LA20
The
TXDATA
/LA20 pin may be configured to operate as
input or output and may be configured to drive inverted
transmit data. Note that some functionality is only
available in PCMCIA mode. Pin functionality is pro-
grammed according to the following table:
The
TXDATA
signal is the inverse of the TXDATA signal
which is the TX data drawn from the TX FIFO using the
internal TX state machine control.
Note that a read of the TXDATALD bit (TCR7[0]) will al-
ways give the current

/LA20 pin value without
inversion, regardless of pin configuration setting.

able in PCMCIA mode. Pin functionality is programmed
according to the following table:
Note that a read of the LLOCKE bit (TIR11[4]) will al-
