Function
Write (Intel/Infineon Mode)
Indicates a write access.
Read/Write (Motorola Mode)
Indicates the direction of the data transfer on the bus.
Address Latch Enable
Controls the on-chip address latch in multiplexed bus mode.
While ALE is ’high’, the latch is transparent. The falling edge
latches the current address. ALE is also evaluated to
determine the bus mode
(ALE fix ’low’ = Motorola, fix ’high’ = Intel/Infineon)
Microprocessor Bus 8/16-Bit Interface Selection
(’low’ = 8 bit, ’high’ = 16 bit)
Interrupt Request
This pin is programmable to push/pull (active high or low) or
open-drain. This signal is activated when SWITI requests
an µP interrupt. When operated in open drain mode,
multiple interrupt sources may be connected.
Address Bus
When operated in address/data multiplex mode, the
address pins are externally connected to the D bus.
Data bus
System Reset
SWITI is forced to go into reset state.
