Function
Write
Indicates a write access to the registers (Intel
bus mode).
Read/Write
A HIGH identifies a valid host access as a read
operation and a LOW identifies a valid host
access as a write operation (Motorola bus
mode).
Address Latch Enable
An address on the external address/data bus
(multiplexed bus type only) is latched with the
falling edge of ALE.
ALE also selects the microcontroller interface
type (multiplexed or non multiplexed).
Reset:
Low active reset input. Schmitt-Trigger input
with hysteresis of typical 360 mV. Tie to ’1’ if not
used.
Reset Output:
Low active reset output.
Interrupt Request:
INT becomes active if the Q-SMINT I requests
an interrupt.
Microcontroller Clock:
Clock output for the microcontroller
Tie to ‘1‘
External Awake:
A low level on EAW during power down
activates the clock generation of the Q-
SMINT I, i.e. the IOM -2 interface provides
FSC, DCL and BCL for read and write
access.
