L64118 MPEG-2 Transport Controller with Embedded MIPS CPU (TR4101)
The EBus controller registers let the user program customized timing for
each address space used in a given system. Six address spaces are
supported, each with a dedicated chip select output.
The main features of the EBus are:
32-bit physical addressing space
32-bit data width
Synchronized to 27 MHz clock
Five external interrupt ports
The EBus supports the following main signals:
32-bit multiplexed address/data
8-bit demultiplexed (low order) address bits
RDn
WRn
EACKn
ALE (Address latch enable)
Five dedicated chip-selects and one multiplexed (with memory
strobe) chip select
4-bit byte enable bus
27 MHz output clock
Peripherals
The L64118 integrates several serial and parallel ports, providing a high
degree of connectivity to various types of peripherals. The
communication ports include:
Three 8251 RS232 serial communication ports connect the set-top
box to a dumb monitor, modem, or PC. The modem communicates
between the subscriber and the main station, or back channel.
One serial I/O includes a V24-compatible UART for a glueless
connection to modem datapump ICs.
