GQSPI_POLL_CFG (QSPI) Register Bit-Field Summary
Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
EN_MASK_UPPER | 31 | rwNormal read/write | 0x0 | Enable Upper Data bus mask: Software Driver name: XGQSPIPS_POLL_UPPER 0: Disable. 1: Enable. Note: Change this value only when controller is not polling. |
EN_MASK_LOWER | 30 | rwNormal read/write | 0x0 | Enable Lower Data bus mask: Software Driver name: XGQSPIPS_POLL_LOWER 0: Disable. 1: Enable. This is a static signal - should not be changed while polling operation is in progress. |
Reserved | 29:16 | razRead as zero | 0x0 | reserved |
MASK_EN | 15:8 | rwNormal read/write | 0x0 | Data bus mask value during Poll operation Software Driver name: XGQSPIPS_POLL 0: Do not mask the bit 1: Mask the bit When any of the 8 bits are set, the specific bit(s) will be masked during Poll operation and comparison with received data against the POLL_DATA field will not consider these bits. When all the bits are zero, no masking is used and all the 8 bits of POLL_DATA field will be used for comparison during Poll. Note: Change this value only when controller is not polling. |
DATA_VALUE | 7:0 | rwNormal read/write | 0x0 | Poll data value. When Poll bit of Generic FIFO is set, Generic QSPI Controller continuously reads the data and checks with the POLL_DATA value. When the received data matches with the POLL_DATA filed, Generic QSPI Controller continues executing the next entry in the Generic FIFO. If the value is not matched and EN_POLL_TIMEOUT is set, poll operation will be terminated after POLL_TIMEOUT clock cycles. This is a static signal - should not be changed while polling operation is in progress. Software Driver name: XGQSPIPS_POLL_DATA |
