Applications
The bit-banging pattern is created by writing and reading the array rows to the port as fast
as the CPU allows. The instructions to implement the shaded part of Figure 9-26 (indicated
by "repeat") are listed below. They are needed to perform one test clock cycle along with the
data signals. Assuming the output array address is located in address register A0, the input
array address is in address register A2, with the I/O port located at address A1 and the
length of the pattern in D0, one repeat cycle is as follows:
