Table 8-70 Tx Buffer Add Request Transmission Occurred Field Descriptions
BitFieldTypeResetDescription
31:0TO31 to TO0R0Transmission Occurred
Each Tx Buffer has its own Transmission Occurred bit. The bits are set when the corresponding TXBRP bit is cleared after a successful transmission. The bits are reset when a new transmission is requested by writing a ‘1’ to the corresponding bit of register TXBAR.
0 - No transmission occurred
1 - Transmission occurred
