The protocol sequence for reading three bytes with
subaddress access is illustrated in Fig.42. The procedure
for this read operation is detailed below:
1. Address slave, write to IICTFR (see Fig.43):
2. Wait until BUSY = 0
3. Check ERR bit, if it is inactive the slave target is
4. Transfer data, write attribute information to IICTFR
5. Wait until BUSY = 0
6. Check ERR bit, if it is inactive IICTFR contains valid

Instead of checking the general error flag (ERR) after each
single 3-byte sequence, it is possible to check the ERR at
the end of the whole protocol sequence. During a bus
cycle, the BUSY bit is set HIGH. At the end of a bus cycle
an interrupt request is generated if enabled and BUSY is
cleared if no error occurs. Writing to the IICTRF should not
be done while the BUSY bit is active, otherwise the ERR
flag will be set HIGH. If no transfer errors occur during the
three transfer actions, the ERR bit will be set LOW. If an
error occurs the ERR bit will be set HIGH and the BUSY bit
stays HIGH. In this case the error and BUSY flags have to
be cleared before starting a new operation.
