6.1.2
In power down mode nRF24L01 is disabled with minimal current consumption. In power down mode all the
register values available from the SPI are maintained and the SPI can be activated. For start up time see
Table 13. on page
6.1.3
By settting the PWR_UP bit in the CONFIG register to 1, the device enters standby-I mode. Standby-I mode
is used to minimize average current consumption while maintaining short start up times. In this mode part
of the crystal oscillator is active. This is the mode the nRF24L01 returns to from TX or RX mode when CE
is set low.
In standby-II mode extra clock buffers are active compared to standby-I mode and much more current is
used compared to standby-I mode. Standby-II occurs when CE is held high on a PTX device with empty TX
FIFO. If a new packet is uploaded to the TX FIFO, the PLL starts and the packet is transmitted.
