Power Control
VIN_PWR_BAD# connects to Carrier Board main power input & discharge circuit. Inactive when main supply is stable
CARRIER_PWR_ON used as enable for Carrier Board main 5V supply & discharge circuit
RESET_IN# to/from carrier board connects to devices requiring full system reset, and to system reset sources (reset button, etc.)
RESET_OUT# to the module from Carrier Board when a force reset is required (as for Boundary Scan test mode)
POWER_BTN# connects to button or similar to pull POWER_BTN# to GND when pressed/asserted to power system ON/OFF
SLEEP# connects to button or similar to pull SLEEP# to GND when pressed/asserted to put system in sleep mode
CARRIER_STBY# connects to enable of supplies that should be off in Sleep mode such as VDD_3V3_SLP
Power Discharge
VIN_PWR_BAD# connects to Carrier Board main power input & discharge circuit. Inactive when main supply is stable
