Receive processing: When receive completes and RX1_END turns ON, use the table move instruction (TMOV) to transfer the content of RX1_DAT[0] - [128] to TX1_DAT[0] - [128]. Then turn OFF RX1_END to complete the receive processing and turn TX1_GO ON to activate the transmit processing.

Receive processing: When receive completes, turn ON RX2_END and use the table move instruction (TMOV) to transfer the content of RX2_DAT[0] - [128] to TX2_DAT[0] - [128]. Then turn RX2_END OFF to complete the receive process and turn TX2_GO ON to activate the transmit process.
