Operating Modes

Mode 1 - (Strobed Input/Output). This functional conﬁgura-

tion provides a means for transferring I/O data to or from a

speciﬁed port in conjunction with strobes or “hand shaking”

signals. In mode 1, port A and port B use the lines on port C

to generate or accept these “hand shaking” signals.

Mode 1 Basic Function Deﬁnitions:

• Two Groups (Group A and Group B)

• Each group contains one 8-bit port and one 4-bit

control/data port

• The 8-bit data port can be either input or output. Both

inputs and outputs are latched.

• The 4-bit port is used for control and status of the 8-bit

port.

Input Control Signal Deﬁnition

(Figures 6 and 7)

STB (Strobe Input)

A “low” on this input loads data into the input latch.

IBF (Input Buffer Full F/F)

A “high” on this output indicates that the data has been

loaded into the input latch: in essence, and acknowledg-

ment. IBF is set by STB input being low and is reset by the

rising edge of the RD input.
