Microcomputer interface terminal list
Type Direction
HTYPE = L
It works as HACK# (acknowledge) output terminal for connection to
Motorola type microcomputer.
It can be used as the weight terminal for connection to the general pur
pose microcomputer. For 3-state output, connect the pull-up resistor.
Interrupt request. If interrupt status register is read, interrupt is masked or
3-S O device is reset, the signal is deasserted.
For 3-state output, connect the pull-up resistor.
The bus width of the microcomputer interface If the device is worked as
CD-G decoder or CD-DSP is connected, select the 8-bit bus mode.
I I Fix it before power up.
L=8bit bus mode
H=16bit bus mode
When HWID is H (16-bit bus MODE), byte order is set.
Setting is valid only when HWID is H.
I I Fix it before power up.
L=HD [15:8] is regarded as m.s. byte. (Motorola type)
H=HD [7:0] is regarded as m.s. byte. (Intel type)
Bus type of microcomputer interface is set.
Fix it before power up.
I I
L=Motorola type
H=General purpose type
I I RESET is input.
3-S O It is output to indicate the idle state.
