The following table explains the FSK Control Register bits.
FSK Package Format automatically amends a ‘start bit’ (Space) to the head of the FSK transmit data and one or two
‘stop bits’ (Mark) to the end, depending on programming of FSKC:STOP. “Res” in the register map means Reserved.
FSK Transmit Register, FSK[7:0], is a WRITE ONLY register. Data written to this register will be placed into the
Internal FIFO for transmission. Note: Reading this register will always give 0x00 as data.
