DESCRIPTION
Ready Acknowledge:
NOTE: This pin must be connected to VDD via 3 kΩ ± 1% resistor.
INTERRUPT Output:
A transition to “Low” indicates that an interrupt has been generated. The inter-
rupt function can be disabled by clearing the interrupt enable bit in the Channel
Control Register.
NOTES:
1. This pin will remain asserted “Low” until the interrupt is serviced.
2. This pin must be conneced to VDD via 3 kΩ ± 1% resistor.
ADDRESS BUS:
8 bit address bus for the microprocessor interface
DATA BUS:
8 bit Data Bus for the microprocessor interface
