BnDm<7:0>: Receive Buffer n Data Field Byte m bits (where 0 ≤ n < 3 and 0 < m < 8)
Each receive buffer has an array of registers. For example, Receive Buffer 0 has 7 registers: B0D0 to
B0D7.
Note 1: These registers are available in Mode 1 and 2 only.

BnDm<7:0>: Transmit Buffer n Data Field Byte m bits (where 0 ≤ n < 3 and 0 < m < 8)
Each transmit buffer has an array of registers. For example, Transmit Buffer 0 has 7 registers: TXB0D0
to TXB0D7.
Note 1: These registers are available in Mode 1 and 2 only.
