2.2
The MCU provides control for the 802.15.4 modem. The required interconnects between the devices are
routed onboard the SiP. In addition, the signals are brought out to external pads primarily for use as test
points. These signals can be useful when writing and debugging software.

During low power modes, input must remain driven by MCU.
By default MISO is tri-stated when CE is negated. For low power operation, miso_hiz_en (Bit 11, Register 07) should be set
to zero so that MISO is driven low when CE is negated.

MC13211/212/213 Technical Data, Rev. 1.8
Modem GPIO2 output acts as “CRC Valid” status indicator for Stream Data
Mode to MCU.
Modem GPIO1 output acts as “Out of Idle” status indicator for Stream Data
Mode to MCU.
MCU Port D Bit 0 drives the attention (ATTN) input of the modem to wake
modem from Hibernate or Doze Mode.
MCU SPI master SPI clock output drives modem SPICLK slave clock input.
MCU SPI master MOSI output drives modem slave MOSI input
Modem SPI slave MISO output drives MCU master MISO input
MCU SPI master SS output drives modem slave CE input
Modem interrupt request M_IRQ output drives MCU IRQ input
MCU Port D Bit 1 drives the RXTXEN input to the modem to enable TX or RX
or CCA operations.
MCU Port D Bit 3 drives the reset M_RST input to the modem.
