BROADCAST_RESET

All devices:

ADDRESS = 0x?? (unknown)

expected = # devices in stack

Note: validated = one more than

devices found at this point

Assign ADDRESS

Write Dev[0]ADDR_CTRL = n

n < look_for?

n < expected?

n == expected?

Dev[n]ADDR_CTRL[]

= n?

Assign unique address (n) to

this device @address 0x00

Validation test: Read same

device for unique address (n)

just assigned

Validate device was

successfully found and

addressed

This loop finds one

device per iteration

new

(Implied: n == look_for here)

Success

All devices found?

START

look_for = 0;

Error()

look_for++;

n = 0;

Read Dev[n]

ADDR_CTRL[]

n++;

This loop resets all addressed

devices, then looks for all

previously found+1 devices

again. Corrects any

addressing faults in the stack

(Implied: n == expected here)
