Table 142 - TX FIFO Write Register
register 1 (EOP and FA), and the resulting 10 bit word is written to the
TX FIFO. The FIFO status is not changed immediately after a write or
read occurs. It is updated after the data has settled and the transfer to
the last available position has finished.
Address 26 - 20. A seven bit address used for comparison with the
second byte of the received address. ADR26 is MSB. This mask is
ignored (as well as first byte mask) if all call address (1111111) is
received.
Second Address Comparison Enable. When this bit is set high, the
above seven bit address is used in the comparison of the second
address byte.
If address recognition is enabled, any packet failing the address
comparison will not be stored in the RX FIFO. A2EN must be high for
All-call address recognition. When this bit is low, this bit mask is ignored
in address comparison
This eight bit word is tagged with the two status bits from the control
Address 16 - 11. A six bit address used for comparison with the first
byte of the received address. ADR16 is MSB.
Address 10. This bit is used in address comparison if a seven bit
address is being checked for (control bit four of control register 2 is set).
First Address Comparison Enable. When this bit is high, the above six
(or seven) bit address is used in the comparison of the first address
byte.
If address recognition is enabled, any packet failing the address
comparison will not be stored in the RX FIFO. A1EN must be high for
All-call (1111111) address recognition for single byte address. When
this bit is low, this bit mask is ignored in address comparison
