Datasheet, Confidential - Prog ramming Sequen ce r s

The program memory areas are setup using start_addr1...start_addr3:

The actual program execution of the sequencers is defined by the program counters PC1...PC3:

Sequencers

All three sequences are autonomous program execution unit executing the commands described in Sequencer Com-

mands Table (see page 66). Programs are downloaded, started and stopped as described in Program Downloading

(see page 43). The output of these sequencers is used for the PWM generator defined by so called MUX tables:
