The Exec_Mode register defines the sequencer executing mode (e.g. single step or run):

5:4

p3_en

00b

R/W

Execution enable for sequencer 3

Sequencer 3 is disabled

Reload program counter and enable:

set PC3 to start_addr3, initialize sequencer 3 internal

loop counters then set p3_en=10 (run)

Execute sequencer commands as defined by

p3_mode

don’t use

1. If all sequencers are switched off (p1_en=00, p2_en=00 and p3_en=00), LED1_on...LED9_on control the oper-

ation of the LEDs - see Current Sources on page 15
