B&B Electronics 2IQEC2 Counter Mode Registers Write to Control Address, Filter Clock Prescalers

Page 11

Filter Clock Prescalers

Each PSC is an 8-bit programmable modulo-N down counter, driven by the FCK clock. The factor N is downloaded into a PSC from the associated PR low byte register PR0. The PSCs provide the ability to generate independent filter clock frequencies for each channel.

Final filter clock frequency

FFCKn=fFCK/(n+1), where n=PSC=0 to 255

Counter Mode Registers (Write to Control Address)

The counter’s operational mode is programmed by writing a byte into the counter mode registers (CMRs).

Definitions of count modes

Range Limit. In range limit count mode, an upper and a lower limit is set, mimicking limit switches in the mechanical counterpart. The upper limit is set by the contents of the PR and the lower limit is set to be 0. The CNTR freezes at CNTR=PR when counting up and at CNTR=0 when counting down. At either of these limits, the counting is resumed only when the count direction is reversed.
