7.4. Reset of the Chip
A power-on reset of the SX1210 is triggered at power up. Additionally, a manual reset can be issued by controlling
pin 13.
7.4.1. POR
If the application requires the disconnection of VDD from the SX1210, despite of the extremely low Sleep Mode
current, the user should wait for 10 ms from of the end of the POR cycle before commencing communications over
the SPI bus. Pin 13 (TEST8) should be left floating during the POR sequence.

Please note that any CLKOUT activity can also be used to detect that the chip is ready.
7.4.2. Manual Reset
A manual reset of the SX1210 is possible even for applications in which VDD cannot be physically disconnected.
Pin 13 should be pulled high for a hundred microseconds, and then released. The user should then wait for 5 ms
before using the chip.
