SPCR3 contains QSPI configuration parameters. The CPU can read and write SPCR3, but the QSM
has read-only access.
Bits [15:11] — Not Implemented
LOOPQ — QSPI Loop Mode
0 = Feedback path disabled
1 = Feedback path enabled
LOOPQ controls feedback on the data serializer for testing.
HMIE — HALTA and MODF Interrupt Enable
0 = HALTA and MODF interrupts disabled
1 = HALTA and MODF interrupts enabled
HMIE controls CPU interrupts caused by the HALTA status flag or the MODF status flag in SPSR.
HALT — Halt
0 = Halt not enabled
1 = Halt enabled
When HALT is asserted, the QSPI stops on a queue boundary. It is in a defined state from which it can
later be restarted.
SPSR contains QSPI status information. Only the QSPI can assert the bits in this register. The CPU
reads this register to obtain status information and writes it to clear status flags.
SPIF — QSPI Finished Flag
0 = QSPI not finished
1 = QSPI finished
SPIF is set after execution of the command at the address in ENDQP[3:0].
MODF — Mode Fault Flag
0 = Normal operation
1 = Another SPI node requested to become the network SPI master while the QSPI was enabled
in master mode (SS input taken low).
The QSPI asserts MODF when the QSPI is the serial master (MSTR = 1) and the SS input pin is negat-
ed by an external driver.
HALTA — Halt Acknowledge Flag
0 = QSPI not halted
1 = QSPI halted
HALTA is asserted when the QSPI halts in response to CPU assertion of HALT.
Bit 4 — Not Implemented
SPCR3 — QSPI Control Register
