14.4.1.1 Receive RAM
Data received by the QSPI is stored in the receive RAM segment located at 0x10 to 0x1F
in the QSPI RAM space. The user reads this segment to retrieve data from the QSPI. Data
words with less than 16 bits are stored in the least significant bits of the RAM. Unused bits
in a receive queue entry are set to zero upon completion of the individual queue entry.
QWR[CPTQP] shows which queue entries have been executed. The user can query this
field to determine which locations in receive RAM contain valid data.
Throughout
consistently and exclusively to designate a 16-bit data unit. The
only exceptions to this appear in discussions of serial
communication modules such as QSPI that support
variable-length data units. To simplify these discussions the
functional unit is referred to as a ‘word’ regardless of length.
