SPCR2 contains QSPI queue pointers, wraparound mode control bits, and an interrupt
enable bit. The CPU32 has read/write access to SPCR2, but the QSM has read ac-
cess only. SPCR2 is buffered. New SPCR2 values become effective only after com-
pletion of the current serial transfer. Rewriting NEWQP in SPCR2 causes execution to
restart at the designated location. SPCR2 reads return the value of the register, not
the buffer.
This field contains the last QSPI queue address.
This field contains the first QSPI queue address.
SPCR3 contains the loop mode enable bit, halt and mode fault interrupt enables, and
the halt control bit. The CPU has read/write access to SPCR3, but the QSM has read
access only. SPCR3 must be initialized before QSPI operation begins. Writing a new
value to SPCR3 while the QSPI is enabled disrupts operation. SPSR contains infor-
mation concerning the current serial transmission. Only the QSPI can set bits in SPSR.
The CPU reads SPSR to obtain QSPI status information and writes it to clear status
flags.
RESET:
RESET:
0 = QSPI interrupts disabled
1 = QSPI interrupts enabled
0 = Wraparound mode disabled
1 = Wraparound mode enabled
0 = Wrap to pointer address $0
1 = Wrap to address in NEWQP
0 = Feedback path disabled
1 = Feedback path enabled
