TWI: STOP not generated
If the sequence described as follows occurs:
then STOP is not generated.
The line will show : DADR BYTE 1, ..., BYTE n, NO STOP generated, BYTE 1, ..., BYTE n.
Insert a delay of one TWI clock period before step 4 in the sequence above.
1. WRITE 1 or more bytes at a given address.
2. Send a STOP.
3. Wait for TXCOMP flag.
4. READ (or WRITE) 1 or more bytes at the same address.
