(c) Subsequent bytes of Tx data should be written to the TXDATA register as soon as the
TXDATAF bit has been set to”1”. After the last byte of Tx data has been loaded, the
TXDATAF bit will be set after both 8 and 16 FFSK bit-periods followed by the TXIDLEF bit
which will be set approximately one FFSK bit-period later, to indicate that the final bit has
been transmitted.
(d) The TXDATAF bit will continue to be set every 8 FFSK bit-periods, regardless of whether Tx
data is written to the TXDATA register or not, providing the transmitter is enabled (FFSK Tx
mode = FFSKTX bit set to “1”). Note that whilst the 2-byte checksum is being generated and
transmitted, the TXDATAF bit will not be set for approximately 24 FFSK bit-periods.
