CNTR No.: Counter Number Bits

(Word 0, Bits 08 and 09)

These two bits select the counter to which this programming block is

applied. The counter number and range number must correspond to a

valid combination as determined by the information in the Module

Setup Block. See Range Allocation Values on page 4-8.

The valid range of this parameter is dependent on the programmed

operating mode.

Rtype: Range Type

(Word 0, Bit 10)

When this bit equals zero, the range specified in this block is a count

range. The output state is active when the count value of the

associated counter is within the programmed range.

When this bit equals one, the range specified is a rate range. The

output state is active when the rate value of the associated counter is

within the programmed range.

Range No.: Range Number Bits

(Word 1, Bits 00 to 15)

These bits define which ranges (0-15) will be programmed or reset. If

a bit is set (1), the corresponding range is programmed. The number

of ranges available is programmed with the range allocation

parameters in the Module Setup programming block.
