Registers

One last event mode, 000BIN, disables the cascade effect and sets up PG4# going true as the trigger event. FS#

must be pulled high before tPGD elapses, or VGATE and all of the PG[4:1]# outputs are disabled.

Cascade enabled:

ENPGA enables PG2#, PG3# and PG4#;

ENPGB enables PG3# and PG4#;

ENPGC enables PG4#.

Cascade disabled:

ENPGA enables PG2#;

ENPGB enables PG3#;

ENPGC enables PG4#.

Simultaneous:

PG1#, PG2#, PG3# and PG4# operate independently from one another.

Sequenced:

PG1#, PG2#, PG3# and PG4# are dependent upon activation of PG(N–1) — for N = 2, 3, and 4 — plus a

programmable PG delay.p=On
