MOTOROLA
Data that is to be transmitted by the QSPI is stored in this segment. The CPU32
normally writes one word of data into this segment for each queue command to be
executed. 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 serializer for transmission. Information re-
mains in transmit RAM until overwritten.
Command RAM is used by the QSPI when in master mode. The CPU32 writes one
byte of control information to this segment for each QSPI command to be executed.
The QSPI cannot modify information in command RAM.
Command RAM consists of 16 bytes. Each byte is divided into two fields. The periph-
eral chip-select field enables peripherals for transfer. The command control field pro-
vides transfer options.
A maximum of 16 commands can be in the queue. Queue execution proceeds from
the address in NEWQP through the address in ENDQP (both of these fields are in
SPCR2).
0 = Control of chip selects returned to PORTQS after transfer is complete.
1 = Peripheral chip selects remain asserted after transfer is complete.
0 = Eight bits
1 = Number of bits set in BITS field of SPCR0.
0 = Delay after transfer is 17
1 = SPCR1 DTL[7:0] specifies delay after transfer PCS valid to SCK.
