or the contents of MCU registers can be logged also. Part of the logging
feature is the ability of the MMDS/MMEVS host software to write the
results of a logging session to an ASCII text file. This text file provides
the means for the MMDS/MMEVS software to communicate with
K3EEPROG even though the host software has exited to the DOS
prompt.
Software Implementation
K3EEPROG’s implementation starts with the design of the code used to
program and read the PEEPROM. As mentioned earlier, the PEEPROM
is composed of 128 bits arranged in a 16 row x 8 column matrix. This
arrangement is analogous to 16 bytes with each column corresponding
to bit positions within the byte. Data can be accessed only one bit at a
time through the manipulation of two registers: the PEEPROM bit select
register (PEBSR) and the PEEPROM status/control register (PESCR).
The PEEPROM bit select register, illustrated in
Figure 1
, is located at
$0E and selects the next PEEPROM bit on which a PEEPROM read or
programming operation is to be performed. An individual bit can be
selected by setting bits 3–6 of the register to the row or byte in which the
bit resides and setting bits 0–2 to the bit’s location within the row or by
writing the bit’s position, 0–127, in the array.
