As it is impossible to know the exact number of data to receive/send, the use of PDC is NOT rec-
ommended in SLAVE mode.
The read mode is defined as a data requirement from the master.
After a START or a REPEATED START condition is detected, the decoding of the address
starts. If the slave address (SADR) is decoded, SVACC is set and SVREAD indicates the direc-
tion of the transfer.
Until a STOP or REPEATED START condition is detected, TWI continues sending data loaded
in the THR register.
If a STOP condition or a REPEATED START + an address different from SADR is detected,
SVACC is reset.

Notes:
The write mode is defined as a data transmission from the master.
After a START or a REPEATED START, the decoding of the address starts. If the slave address
is decoded, SVACC is set and SVREAD indicates the direction of the transfer (SVREAD is low in
this case).
Until a STOP or REPEATED START condition is detected, TWI stores the received data in the
RHR register.
If a STOP condition or a REPEATED START + an address different from SADR is detected,
SVACC is reset.
