I/O
An eight bit bi-directional data bus that provides the data into the LIU for a Write
operation or the data out to the Host for a Read operation.
P26
INT
O
Interrupt Active Output (active low)
Normally, this output pin will be pulled "High". However, if the user enables
interrupts within the LIU, and if those conditions occur, the XRT75R12 will sig-
nal an interrupt from the Microprocessor by pulling this output pin "Low". The
Host Microprocessor must ascertain the source of the interrupt and service it.
Reading the source of the interupt will clear the flag and the INT pin will go back
high unless another interrupt has gone active.
NOTES:
1.
This pin will remain "Low" until the Interrupt has been serviced.
2.
This pin must be pulled "High" with a 3k
± 1% resistor.
N2
RESET
I
RESET Input
Pulsing this input "Low" causes the XRT75R12 to reset the contents of the on-
chip Command Registers to their default values. As a consequence, the
XRT75R12 will then also be operating in its default condition.
For normal operation this input pin should be at a logic "High".
NOTE: This input pin is internally pulled high.
