Program and use the modem IO pins properly for low power operation
— All unused modem GPIOx signals must be used one of 2 ways:
— When modem GPIO are used as outputs:
— If the modem GPIO is used as an input, the GPIO should be driven by its source during all low
— Digital outputs IRQ, MISO, and CLKO:

Mode of oscillation
User must be sure manufacturer specifications apply to the desired package.
A wider frequency tolerance may acceptable if application uses trimming at production final test.
A wider frequency stability may be acceptable if application uses trimming at production final test.
A wider aging tolerance may be acceptable if application uses trimming at production final test.
Higher ESR may be acceptable with lower load capacitance.
Lower load capacitance can allow higher ESR and is better for low temperature operation in Doze mode.
Low Power Considerations
– If the Off mode is to be used as a long term low power mode, unused GPIO should be tied
– If only Hibernate and/or Doze modes are used as long term low power modes, the GPIO
– Pullup resistors should be provided (can be provided by the MCU IO pin if tied to the MCU)
– During Hibernate and/or Doze modes, the GPIO will retain its programmed output state.

– MISO - is always an output. During Hibernate, Doze, and active modes, the default

if the modem Off condition is to be used as a long term low power mode.
condition is for the MISO output to go to tristate when CE is de-asserted, and this can cause
a problem with the MCU because one of its inputs can float. Program Control_B Register

toggle. During Doze, CLKO may toggle depending on whether it is being used.
It is good practice to have the IRQ interrupt input to the MCU disabled
during the hardware reset to the modem. After releasing the modem
hardware reset, the interrupt request input to the MCU can then be enabled
to await the IRQ that signifies the modem is ready and in Idle mode; this can
prevent a possible extraneous false interrupt request.
