QSM
REFERENCE MANUAL
FRZ1 — Freeze 1
1 = Halt the QSM (on a transfer boundary)
0 = Ignore the FREEZE signal on the IMB
FRZ0 — Freeze 0
Reserved for future enhancement.
Bits [12:8] — Not Implemented
SUPV — Supervisor/Unrestricted
1 = Supervisor access
0 = User access
Bits [6:4] — Not Implemented
IARB — Interrupt Arbitration Identification Number
System software should initialize the IARB field to a value between $F (top priority)
and $1 (lowest priority). Otherwise, any interrupts generated are identified by the CPU
as spurious.
TSBD — SPI Test Scan Path Select
1 = Enable delay to SCK scan path
0 = Enable SPI baud clock scan path
SYNC — SCI Baud Clock Synchronization Signal
1 = Inhibit SCI source signal (QCSCI1)
0 = Activate SCI source signal
TQSM — QSM Test Enable
1 = Enable QSM to send test scan paths
0 = Disable scan path
TMM — Test Memory Map
1 = QSM responds to test memory addresses.
0 = QSM responds to QSM memory addresses.
* QIVR — QSM Interrupt Vector Register
ILQSPI — Interrupt Level for QSPI
ILQSPI determines the priority level of all QSPI interrupts. Program this field to a value
QTEST
— QSM Test Register
