ic_status

This is a read-only register used to indicate the current transfer status and FIFO status. The status register may be read at any time. None of the bits in this register request an interrupt.When the I2C is disabled by writing 0 in bit 0 of the ic_enable register: - Bits 1 and 2 are set to 1 - Bits 3 and 4 are set to 0 When the master or slave state machines goes to idle - Bits 5 and 6 are set to 0

Important: To prevent indeterminate system behavior, reserved areas of memory must not be accessed by software or hardware. Any area of the memory map that is not explicitly defined as a register space or accessible memory is considered reserved.

slv_activity

Slave FSM Activity Status. When the Slave Finite State Machine (FSM) is not in the IDLE state, this bit is set.

Value	Description
0x0	Slave FSM is in IDLE state so the Slave part of i2c is not Active
0x1	Slave FSM is not in IDLE state so the Slave part of i2c is Active

RO

0x0

mst_activity

When the Master Finite State Machine (FSM) is not in the IDLE state, this bit is set. Note:IC_STATUS[0]-that is, ACTIVITY bit-is the OR of SLV_ACTIVITY and MST_ACTIVITY bits.

Value	Description
0x0	Master FSM is in IDLE state. Master part of i2c is not Active
0x1	Master FSM is not in IDLE state. Master part of i2c is Active

RO

0x0

rff

Receive FIFO Completely Full.

Value	Description
0x0	Receive FIFO is not full
0x1	Receive FIFO is full

RO

0x0

rfne

Receive FIFO Not Empty.

Value	Description
0x0	Receive FIFO is empty
0x1	Receive FIFO is not empty

RO

0x0

tfe
