• TXCTL_TBL—The transmit control character table stores the bit array used for the TX
control character table. Each bit corresponds to a character that must be mapped
according to RFC 1549. If the bit is set, the character corresponding to that bit is
mapped and if the bit is not set, the corresponding character is not mapped. The
transmit control character table must be initialized to zero for IrLAP.

• RXCTL_TBL—The receive control character table stores the bit array used for the RX
control character table. Each bit corresponds to a character that must be mapped
according to RFC 1549. If the bit is set, the character corresponding to that bit is
discarded if received and if the bit is not set, the corresponding character is received
normally. The receive control character table must be initialized to zero for IrLAP.

• NOF—This entry must be initialized to the number of opening flags to be transmitted at
the beginning of a frame. A value of n corresponds to n +1 flags.
