Signal Name:
Signal Description:
Signal Type:
This signal is an open-drain output that will be forced low if one or more unmasked interrupt sources
within the device is active. The signal will remain low until either the interrupt is serviced or masked.
Signal Name:
Signal Description:
Signal Type:
This active low signal must be asserted for the device to accept a read or write command from an external
host.
Signal Name:
Signal Description:
Signal Type:
This input signal controls a latch that exists on the CA0 to CA7 inputs. When CALE is high, the latch is
transparent. The falling edge of CALE causes the latch to sample and hold the CA0 to CA7 inputs. In
nonmultiplexed bus applications, CALE should be tied high. In multiplexed bus applications, CA[7:0]
should be tied to CD[7:0] and the falling edge of CALE will latch the address.
