function
When the M32000D4AFP drives an external bus cycle, it
automatically inserts wait cycles until DC is input by the slave
device in the system bus.
When the M32000D4AFP is in the hold state and the internal
DRAM is accessed from an external bus master, the M32000D4AFP
__
outputs DC to notify to the external bus master that the bus
cycle to the internal DRAM has been completed.
Bus right request input pin of the system bus. When HREQ is an
"L" level, the M32000D4AFP switches to the hold state.
Indicates that the M32000D4AFP has switched to the hold state
and releases the bus right of the system bus to the requestor.
Signal input to the M32000D4AFP when it is in the hold state to
request access to the internal DRAM from an external bus master.
__
When an "L"level is input to CS, the M32000D4AFP access
accesses the internal DRAMat the address input via the address
pins.
System break interrupt input pin. The SBI is not masked by the
IE bit in the PSW register. It is also used to return from CPU
sleep mode and to request the start of operation in slave mode.
External interrupt request input pin. It is also used to return from
CPU sleep mode and to request the start of operation the slave
mode.
Two programmable I/O ports.
