function
power
VCC
power source
All power source pins should be connected to VCC.
source
VSS
ground
All ground pins should be connected to VSS.
clock
CLKIN
clock input
input
Clock input pin. The M32000D3FP has an internal PLL
multiplier circuit, and an input clock which is 1/4 of
the internal operating frequency (when the internal
operating frequency is 66.6 MHz, the CLKIN input is
16.65 MHz).
PLLCAP
C connection
Connects a capacitor for internal PLL.
for PLL
PLLVCC
power source
Connects a power source for internal PLL.
for PLL
PLLVSS
ground
Connects ground for internal PLL.

system
____
RST
reset
input
Internally resets the M32000D3FP. It is also used to
control
return from standby mode and CPU sleep mode.
_
M/S
master/slave
input
Sets the M32000D3FP default operation to either system
__
bus master (M/S = "H") or bus slave (M/S = "L").
When the M32000D3FP is set to bus slave, it does
not carry out vector fetching after a reset.
_
The setting of M/S cannot be changed during operation.
Keep at either an "H" or an "L" level.
_____
WKUP
wakeup
input
Input pin to request return from standby mode.
_____
This is only accepted when STBY is "L" level.
It generates the wakeup interrupt.
_____
STBY
standby
output
Indicates that the M32000D3FP has switched to the
standby mode. An "L" level is output while in the standby
mode.
address
A8 to A30
address bus
I/O
The M32000D3FP has a 24-bit address (A8 to A31)
bus
(Hi-z)*
for a 16 MB address space. A31 is not output. During
the write cycle, the valid byte positions on the 16-bit
____
data bus are output as BCH or BCL. During the read
cycle, the 16-bit data bus is read, however, only data
in the valid byte positions is transferred to the
M32000D3FP.
Address bus pins are bidirectional. When accessing
the internal DRAM from an external bus master while
the M32000D3FP is in the hold state, input the address
from the system bus side.
data bus
D0 to D15
data bus
I/O
16-bit data bus for connecting to external device.
(Hi-z)*
* (Hi-z): This pin goes to high-impedance in the hold state.
