MPU_MODE[2:0]: Microprocessor Interface Mode Selection
The device supports five microprocessor interface modes: EPROM, Multiplexed, Intel, Motor-
ola and Serial.
During reset, these pins determine the default value of the MPU_SEL_CNFG[2:0] bits (b2~0,
7FH) as follows:
001 (EPROM mode);
010 (Multiplexed mode);
011 (Intel mode);
100 (Motorola mode);
101 (Serial mode);
110 - 111 (Reserved).
After reset, these pins are general purpose inputs. The microprocessor interface mode is
selected by the MPU_SEL_CNFG[2:0] bits (b2~0, 7FH).
The value of these pins is always reflected by the MPU_PIN_STS[2:0] bits (b2~0, 02H).

A[6:0]: Address Bus
In ERPOM, Intel and Motorola modes, these pins are the address bus of the microprocessor
interface.
SDI: Serial Data Input
In Serial mode, this pin is used as the serial data input. Address and data on this pin are seri-
ally clocked into the device on the rising edge of SCLK.
CLKE: SCLK Active Edge Selection
In Serial mode, this pin selects the active edge of SCLK to update the SDO:
High - The falling edge;
Low - The rising edge.
In Multiplexed mode, A0/SDI, A1/CLKE and A[6:2] pins should be connected to ground.
In Serial mode, A[6:2] pins should be connected to ground.

AD[7:0]: Address / Data Bus
In EPROM, Intel and Motorola modes, these pins are the bi-directional data bus of the micro-
processor interface.
In Multiplexed mode, these pins are the bi-directional address/data bus of the microproces-
sor interface.
SDO: Serial Data Output
In Serial mode, this pin is used as the serial data output. Data on this pin is serially clocked
out of the device on the active edge of SCLK.
In Serial mode, AD[7:1] pins should be connected to ground.

WR: Write Operation
In Multiplexed and Intel modes, this pin is asserted low to initiate a write operation.
In Motorola mode, this pin is asserted low to initiate a write operation or s asserted high to ini-
tiate a read operation.
In EPROM and Serial modes, this pin should be connected to ground.

RD: Read Operation
In Multiplexed and Intel modes, this pin is asserted low to initiate a read operation.
In EPROM, Motorola and Serial modes, this pin should be connected to ground.
