2.4

Interrupt Pin

The SPI_INT line works in conjunction with the SPI

port. It is an active-low output signal to the host MCU to

signal an interrupt event.

2.5

VDD and GND Pin

The MRF24WN0MA/MB wireless module contains an

integrated power management unit that generates all

necessary voltages required by the internal circuitry.

The module is powered from a single voltage source.

Table 2-3 lists the recommended bypass capacitors.

The capacitors must be closely placed to the module.

2.6

Hibernate

The module enters the lowest power mode when the

HIBERNATE pin is asserted low. No state information

is preserved. The MPLAB Harmony framework can

save state information in the host MCU that can be

restored after wake-up (HIBERNATE pin is asserted

high).

The module can wake-up when HIBERNATE pin is

asserted high. The module must be initialized and any

state information saved prior to Hibernate state is

restored. This process approximately takes 40 ms.
