: Chip Selection
A transition from high to low must occur on this pin for each read or write operation and this
pin should remain low until the operation is over.
INT_REQ: Interrupt Request
This pin is used as an interrupt request. The output characteristics are determined by the
HZ_EN bit (b1, 0CH) and the INT_POL bit (b0, 0CH).
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.
