315/433MHz FSK Transceiver
CRCS: CRC select. 1: Select. The CRC is CCITT-16 CRC.
FECS: FEC select. 1: Select. The FEC is (7, 4) Hamming code.
WHTS: Data whitening select. 1: Select. The data is whitening by multiplying PN7.
MCS: Manchester code select. 1: Select.
WS [6:0]: Whitening seed.

SCKI: SPI clock invert. 1: Invert.
CKOE: CKO pin output enable. 0: High Z, 1: Enable.
CKO [1:0]: CKO select.
[00]: BCK (bit clock).
[01]: MRCK (modulation rate).
[10]: FPF (FIFO pointer flag).
[11]: Reversed.
When Manchester code is selected, BCK is the bit clock of Manchester code that equals half modulation rate.
In such case, BCK will appear after TX modulation start in TX mode or internal frame sync in RX mode. On the
other hand, BCK equals modulation rate.
When [11] selected, the output is the logic OR of EOP, EOVBC, EOFBC, EOADC and OKADC.
CKOI: CKO invert. 1: Invert.
IRQE: IRQ pin output enable. 0: High Z, 1: Enable.
IRQ [1:0]: IRQ function select.
TX state
[00] WPLL state & TX state(WTR)
[01] End of Access code (EOAC)
[10] TX modulation enable (TMEO)
[11] None
RX state

Access code matched (FSYNC)
carrier detected (CD)
External FSYNC input ( for direct mode)
When IRQ set to [11] and direct mode is selected, the internal frame sync function will be disabled. In such case, it is
recommended that user assure frame sync signal to this input to get better DC estimation of demodulation.
IRQI: IRQ output invert. 0: normal, 1: Invert.
PCS: TRE and TRS pin control. 0: Register control, 1: Pin control.
