Notes:

1. I = Input, O = Output, S = Supply, NC = No connect

2. The AMW004 RESET_N pin is connected directly to the MCU NRST pin. When the MCU is placed in low-power

BACKUP mode, the NRST pin is disabled and RESET_N can NOT be used to reset the module. To enable reset

when MCU BACKUP mode is used, the RESET_N pin must be connected to one of the WAKE pins, and the

WAKE pin must be enabled via software.

3. Connected to SPI serial flash inside module
