10.8.5.5.1 RF output
When the RFM finishes a transmission sequence the external crystal oscillator (XCO), bit
rate generator, PLL, VCO, RF data buffer, data encoder, and RF output stage will remain
powered up if the SEND bit is set.
10.8.5.6 P-cell in STOP modes
The P-cell is powered up only during a measurement if scheduled by the sensor
measurement interface. Otherwise it is powered down.
10.8.5.7 Optional g-cell in STOP modes
The g-cell is powered up only during a measurement if scheduled by the sensor
measurement interface. Otherwise it is powered down.
10.9 Memory
The overall memory map of the NTM88 resides on the MCU.
