Module Programming Errors

A programming error is caused by improper set up of a module

parameter. The module responds to a programming error by setting

the programming error bit. When this bit is set, the entire

programming block is rejected.

The programming error bit is set when a reserved bit is set. It is also

set under the following conditions:

Module Setup • Operating mode bits are not set to a valid pattern.

• A counter’s range allocation value is greater than 16.

• The sum of all range allocation values is greater than 16.

• The range allocation value for Counter 2 and/or Counter 3 is

nonzero and the programmed operating mode has the counter

disabled.

• A counter or counters were running when the block was sent.
