// Alpha sample workaround - write DLC = 0 before IMSG=1;
#warning "ALPHA SAMPLE WORKAROUND"
// Set IMSG bit to ignore ID if not found!
// Check ID
// Set ID found flag
// Load TX buffers
// Write DLC code to start TX - STD CHECKSUM
// Test message from master
// --------- test code....
// Set ID found flag
// Write DLC code = RX, STANDARD CHECKSUM, 2 bytes
// reset ID_found
// (should do anyway on re-entry into ISR)
// Clear LINSleep flag-due to bus activity
// Load RAM from RX buffers
