SERIAL PERIPHERAL INTERFACE (SPI) TIMING CHARACTERISTICS
(SPI timing characteristics are valid for both 3V and 5V modes. SPI timing is production tested at worst-case temperature and supply
with a clock frequency of 3MHz.)
Note 1: Supply current and output power are greatly dependent on board layout and PAOUT match.
Note 2: 50% duty cycle at 10kHz ASK data (Manchester coded).
Note 3: Dependent on PCB trace capacitance.
