0: Master interface is disabled.
1: Master interface is enabled.
This bit is one when STOP request caused by setting CR STOP has been accepted, and transfer has stopped.
This bit is cleared by writing 1 to the corresponding bit in the Status Clear Register (SCR).
This bit is one when a SMBus PEC error occurred.
This bit is cleared by writing 1 to the corresponding bit in the Status Clear Register (SCR).
This bit is one when a SMBus timeout occurred.
This bit is cleared by writing 1 to the corresponding bit in the Status Clear Register (SCR).
This bit is one when an SMBus Alert was received.
This bit is cleared by writing 1 to the corresponding bit in the Status Clear Register (SCR).
This bit is one when the actual state of the SDA line did not correspond to the data driven onto it, indicating a higher-priority
transmission in progress by a different master.
This bit is cleared by writing 1 to the corresponding bit in the Status Clear Register (SCR).
This bit is one when no ACK was received form slave during data transmission.
This bit is cleared by writing 1 to the corresponding bit in the Status Clear Register (SCR).
This bit is one when no ACK was received from slave during address phase
This bit is cleared by writing 1 to the corresponding bit in the Status Clear Register (SCR).
This bit is one when activity has completed on the two-wire bus.
