SMT4214, the PWR_ON# pin must be high in order to program the device. It can be done optionally through
the SMX3200 programmer and R1/R2 or through an external control signal or switch. The SMX3200 should
be disconnected after programming the part. If the PWR_ON# is hardwired to ground, this method will not
work. Normally SDA and SCL signals require on board pull-up resistors, however, both the SMT4214 and
the SMX3200 have internal pull-up resistors. D1 and D2 are needed between the Dongle Supplies and the
VDD_CAP and PWR_ON# pins so that there will be no contention between the two supplies. C1 and C2 are
for noise bypassing.
