Address bus input for microcomputer connection.
I I
Used for register access and so on
HTYPE = L
It works as HR/W#(read/write) input terminal for connection to Motorola
type microcomputer.
I I
HTYPE = H
It works as HWR# (write) input terminal for connection to general purpose
microcomputer.
I I Chip select input for connection to microcomputer
HTYPE = L
It works as HDS#(data strobe) input terminal for connection to Motorola
type microcomputer.
I I
HTYPE = H
It works as HRD# (read) input terminal for connection to general purpose
microcomputer.
Bit stream input ready output terminal If the bit stream is input from
microcomputer, the terminal is bored.
For 3-state output, connect the pull-up resistor.
HRDY = L
O Bit stream can not be input.
HRDY = H
The number of bytes which are set by CodBurstLen parameter can be
transferred from the microcomputer. During the time from transfer start of
the number of set bytes to transfer end, the terminal varies in 3 states.
