Type
Default Description PowerWell ResetSignal
Indicates whether a RESTART
condition has occurred on the
I2C interface when I2C
controller is operating in
slave mode and the slave is
the addressed slave.
11 RO 1'b0 General Call
Acknowledged
(GEN_CALL)
Set only when a General Call
address is received and it is
acknowledged. It stays set
until it is cleared either by
disabling the I2C controller or
when the CPU reads bit 0 of
the IC_CLR_GEN_CALL
register. I2C controller stores
the received data in the Rx
buffer.
10 RO 1'b0 Start Detected
(START_DET)
Indicates whether a START or
RESTART condition has
occurred on the I2C interface
regardless of whether the
controller is operating in
slave or master mode.
9 RO 1'b0 Stop Detected
(STOP_DET)
Indicates whether a STOP
condition has occurred on the
I2C interface regardless of
whether the controller is
operating in slave or master
mode.
8 RO 1'b0 Activity (ACTIVITY)
This bit captures I2C
controller activity and stays
set until it is cleared. There
are four ways to clear it:
- Disabling the controller
- Reading the
IC_CLR_ACTIVITY register
- Reading the IC_CLR_INTR
register
- System reset
