9.3.9.5.3 Receiving Data
After a START or repeated START condition is detected, and if the address sent by the host matches the client address programmed in the SADR (Client Address) field, the SVACC (Client Access) flag is set and SVREAD (Client Read) indicates the direction of the transfer.
SVACC remains high until a STOP condition or a repeated START is detected. When such a condition is detected, EOSACC (End Of Client Access) flag is set.
