Bit 6:5 = ICOQ [1:0]: C/QO HS and LS cutoff current

This bit is used to configure the cutoff current value on the C/Q

channel, as shown in Table 14.

Bit 4:3 = tdcoq [1:0]:C/QO HS and LS cutoff current delay time

The channel output driver is turned off after a delay (tdcoq)

programmable by means of these two bits:

Bit 2

= trcoq:

C/QO restart delay time

After a cutoff event, the channel driver automatically restarts after

a delay (trcoq) programmable by means of this bit:
