µPD77016

• External instructions memory interface

Symbol

Pin No.

I/O

Function

IA15 - IA0

Note 1.

O (3S)

Address bus to external instruction memory

• Even the internal instruction memory is accessed, the

address is output to the external instruction memory.

In this case, the

µPD77016 ignores data of external

instruction memory output.

ID31 - ID0

Note 2.

I/O (3S)

32 bits instruction input

PWR

129

O (3S)

Program memory write strobe

• Write strobe for external instruction memory. This pin

loads program to external instruction memory (not

internal memory) while

µPD77016 is in boot operation.

Note 1.

IA15 to IA0 pins are located on these pins: 101 to 104, 107 to 114, 117 to 120

ID31 to ID0 pins are located on these pins: 121 to 128, 132 to 139, 142 to 149, 152 to 159

Remark

The state of the pins added 3S becomes high impedance when RESET is input.

• Debugging interface
