ACK - (Acknowledge Input). A “l(fā)ow” on this input informs the
82C55A that the data from Port A or Port B is ready to be
accepted. In essence, a response from the peripheral device
indicating that it is ready to accept data, (See Note 1).
INTR - (Interrupt Request). A “high” on this output can be
used to interrupt the CPU when an output device has
accepted data transmitted by the CPU. INTR is set when
ACK is a “one”, OBF is a “one” and INTE is a “one”. It is reset
by the falling edge of WR.
INTE A
Controlled by Bit Set/Reset of PC6.
INTE B
Controlled by Bit Set/Reset of PC2.
NOTE:
1. To strobe data into the peripheral device, the user must operate
the strobe line in a hand shaking mode. The user needs to send
OBF to the peripheral device, generates an ACK from the
peripheral device and then latch data into the peripheral device
on the rising edge of OBF.
