L64118 MPEG-2 Transport Controller with Embedded MIPS CPU (TR4101) 47
Infrared Port
These signals provide the connection between the L64118 and an
external infrared receiver and transmitter.
IRBL
Infrared Blaster
Output
This signal is the infrared blaster output. This signal can
be congured to reect the value of the infrared
transmitter output.
GPIO47
Bidirectional
IRBL can serve as a general-purpose I/O signal
(GPIO47) by setting bit 7 in the General-Purpose Mode
register.
By default, this signal oats after reset.
IRRX0
Infrared Receiver 0
Input
This signal serves as the receive port for the
demodulated signal of one of the two infrared receivers
ports.
GPIO40
Bidirectional
IRRX0 can serve as a general-purpose I/O signal
(GPIO40) by setting bit 7 in the General-Purpose Mode
register.
By default, this signal oats after reset.
IRRX1
Infrared Receiver 1
Input
This signal serves as the receive port for the
demodulated signal of one of the two infrared receivers
ports.
GPIO41
Bidirectional
IRRX1 can serve as a general-purpose I/O signal
(GPIO41) by setting bit 7 in the General-Purpose Mode
register.
By default, this signal oats after reset.
