interface
Module/Function Description
Host interface
(HIF)
• On-chip 4-kbyte buffer RAM (two 2-kbyte banks)
• Parallel connection of buffer RAM and external device
with sixteen data pins
• Parallel connection of buffer RAM and the CPU of this LSI
with the internal bus
• A connected external device can access desired register
after the register index was specified (However,
addresses can be automatically updated during
continuous buffer RAM access)
• Endian switchable
• An interrupt can be requested to a connected external
device
• An internal interrupt can be requested to the CPU of this
LSI
• Allows booting from the buffer RAM by storing the
instruction code beforehand from the external device in
the buffer RAM
Serial
communication
interface with
FIFO (SCIF)
• Three channes
• Clock synchronous mode or asynchronous mode
selectable
• Supports simultaneous transmission and reception (full-
duplex communication)
• Dedicated baud rate generator
• Separate 16-byte FIFO registers for transmission and
reception
• Modem control function (asynchronous mode)
