3.5 Self-start Configuration
In order to minimize the GPIO required for operating A5100-A, WAKEUP (pin 19) and
ON_OFF (pin 6) can be tied together for entering the self-start mode such that no
ON_OFF pulse requires. The following picture shows the recommended connection
for self-start configuration with UART host port enabled.

Remarks:
•
For self-start mode, full power operation will be activated once Vcc applied.
No power save mode (PTF / MPM / TP) will be supported. If customer acci-
dentally configuring A5100-A into hibernation mode, Vcc has to be discon-
nected and re-plugged so as to operate the module in full power mode.
