Description
Data Strobe. When low, indicates to the printer that valid
data is available at the printer port. This signal is in TRI-
STATE after a 0 is loaded into the corresponding control
register bit. An external 4.7 KΩ pull-up resistor should be
employed.
Write Strobe. Active low, used in EPP mode to denote
an address or data cycle. When the cycle is aborted,
WRITE# becomes inactive (high).
Description
IR Receive. Primary input to receive serial data from the
IR transceiver. Monitored during power-off for wakeup
event detection.
Note:
IR Receive 2. Auxiliary IR receiver input to support a
second transceiver. This input signal can be used when
GPIO38 is selected using PMR[14], and when
AUX_IRRX bit in register IRCR2 of the IR module in
internal SuperI/O is set.
IR Transmit. IR serial output data.
If selected as IRRX1 function but not used, tie
IRRX1 high.
