Figure 15 QSPI RAM
Once the CPU has set up the queue of QSPI commands and enabled the QSPI, the QSPI can operate
independently of the CPU. The QSPI executes all of the commands in its queue, sets a flag indicating
that it is finished, and then either interrupts the CPU or waits for CPU intervention. It is possible to ex-
ecute a queue of commands repeatedly without CPU intervention.
RR[0:F]
— Receive Data RAM
Data received by the QSPI is stored in this segment. The CPU reads this segment to retrieve data from
the QSPI. Data stored in receive RAM is right-justified. Unused bits in a receive queue entry are set to
zero by the QSPI upon completion of the individual queue entry. The CPU can access the data using
byte, word, or long-word addressing.
$YFFD00
The CPTQP value in SPSR shows which queue entries have been executed. The CPU uses this infor-
mation to determine which locations in receive RAM contain valid data before reading them.
TR[0:F]
— Transmit Data RAM
Data that is to be transmitted by the QSPI is stored in this segment. The CPU usually writes one word
of data into this segment for each queue command to be executed.
$YFFD20
Information to be transmitted must be written to transmit data RAM in a right-justified format. The QSPI
cannot modify information in the transmit data RAM. The QSPI copies the information to its data serial-
izer for transmission. Information remains in transmit RAM until overwritten.
*The PCS0 bit represents the dual-function PCS0/SS.
