Word and bit Numbering
The QDC module stores data in command and status blocks. Each word
location in a command or status block is identified by an alphanumeric
code containing the block acronym and word number. For example, word
09 of the Module Configuration Command Block (MCC) is identified as
MCC09.
Identify bits in a word location by adding bit numbering to the abbreviated
word location. For example:
Specific: MCC09-B15
General: MCCxx-Byy
where:
MCC = Module Configuration Command Block
xx=word number (01-64)
B = bit identifier
yy = bit number (00-15)
The following table lists documentation necessary for the successful
application of the QDC module:
