Panasonic SV-MP100VGC, Service Manual

I/O 0 ~ I/O7: DATA INPUTS/OUTPUTS 
  The I/O pins are used to input command,address and data, and to output data during read operations.

  The I/O pins float to high-z when the chip is deselected or when the outputs are disabled.

Vcc: POWER Vcc is the power supply for device.

Vss: GROUND

R/B: READY/BUSY OUTPUT
  The R/B output indicates the status of the device operation.When low, it indicates that a program, erase or random read operation is in process 
  and returns to high state upon completion.It is an open drain output and does not float to high-z condition when the chip is deselected or when 
  outputs are disabled.

RE: READ ENABLE
  The RE input is the serial data-out control, and when active drives the data onto the I/O bus. Data is valid tREA after the falling edge of RE which 
  also increments the internal column address counter by one.

CE: CHIP ENABLE
  The CE input is the device selection control. When the device is in the Busy state, CE high is ignored, and the device does not return to standby
  mode in program or erase opertion. Regarding CE control during read operation, refer to "Page read" section of Device operation.

CLE: COMMAND LATCH ENABLE
  The CLE input controls the activating path for commands sent to the command register. When active high, commands are latched into the 
  command register through the I/O ports on the rising edge of the WE signal.

ALE: ADDRESS LATCH ENABLE
  The ALE input controls the activating path for address to the internal address registers.Addresses are latched on the rising edge of 
  WE with ALE high.

WE: WRITE ENABLE
  The WE input controls writes to the I/O port. Commands, address and data are latched on the rising edge of the WE pulse.

WP: WRITE PROTECT
  The WP pin provides inadvertent write/erase protection during power transitions. The internal high voltage generator is reset when the 
  WP pin is active low.
