Description
Active LO reset to TFP2 processor.
Active HI signal starts target FLASH Memory programming. A
minimum 200 ms pulse is required.
Active Hi signal indicates target FLASH Memory programming
in progress. De-assert PROGRAM upon PROGRAM ACTIVE
going high.
Active HI signal indicates target FLASH Memory verified to be
correct. PASS goes low when PROGRAM is re-asserted high.
PASS toggles Hi and LO during programming sequence.
