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 connec-

tion

for self-start configuration with UART host port enabled.

Figure 8: Self-start configuration A5100-A

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.
