Does status.TX_MODE = 1?
C: (Interrupt is from Slv receiving data from Mastr)

If Yes, Master wants transmit mode
Exit ISR, indicate Master wants Slv-Xmit mode
If No, Master wants Slave-Recv mode
dummy = S1DAT, read to release bus
Exit ISR, ready to recv data on next interrupt
recv_buf[buffer_index] = S1DAT, read byte
Exit ISR, recv next byte on next interrupt
