GQSPI_POLL_CFG (QSPI) Register Bit-Field Summary

Field NameBitsTypeReset ValueDescription
EN_MASK_UPPER31rwNormal read/write0x0Enable 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_LOWER30rwNormal read/write0x0Enable 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.
Reserved29:16razRead as zero0x0reserved
MASK_EN15:8rwNormal read/write0x0Data
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 7:0rwNormal read/write0x0Poll 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.
