Status Register 0

## Modules§

- ARBCMDSRC
  This status field indicates the trigger source of current command sequence granted by arbitrator. This field value is meaningless when ARB_CTL is not busy (STS0[ARBIDLE]=0x1).
- ARBIDLE
  This status bit indicates the state machine in ARB_CTL is busy and there is command sequence granted by arbitrator and not finished yet on FlexSPI interface. When ARB_CTL state (ARBIDLE=0x1) is idle, there will be no transaction on FlexSPI interface also (SEQIDLE=0x1). So this bit should be polled to wait for FlexSPI controller become idle instead of SEQIDLE.
- SEQIDLE
  This status bit indicates the state machine in SEQ_CTL is idle and there is command sequence executing on FlexSPI interface.
