L64118 MPEG-2 Transport Controller with Embedded MIPS CPU (TR4101) 41
Aux - Packet ID [0]
Output
In Aux mode, this signal is part of a three-bit packet ID
that can be assigned to PIDs that are output to the Aux
port.
GPIO26
Bidirectional
This signal can also serve as a general-purpose I/O
signal (GPIO26) by setting bit 3 in the General-Purpose
Mode register.
SELECT/AUXPID[1]
1284 - Peripheral Select
Output
When set HIGH, this signal indicates that the L64118
IEEE1284 port was selected and is connected to the
host.
Aux - Packet ID [1]
Output
In Aux mode, this signal is part of a three-bit packet ID
that can be assigned to PIDs that are output to the aux
port.
GPIO27
Bidirectional
This signal can also serve as a general-purpose I/O
signal (GPIO27) by setting bit 3 in the General-Purpose
Mode register.
SELECTINn/AUX_ADP/AUX_ERR
1284 - Peripheral Selection Indicator
Input
In 1284 mode, this signal (when asserted LOW) indicates
that the external host is attempting to select a peripheral.
Aux - Adaptation Field Flag
Output
In Aux output mode, this signal functions as AUX_ADP,
which indicates if the output byte is part of an adaptation
eld.
Aux - Error Indicator
Input
In Aux input mode, this signal functions as AUX_ERR,
which indicates if the incoming byte is part of a packet
that has an error.
GPIO28
Bidirectional
This signal can also serve as a general-purpose I/O
signal (GPIO28) by setting bit 3 in the General-Purpose
Mode register.
