Quadrature Encoder (QEI)
Description:
Disables the indicated quadrature encoder interrupt sources. Only the sources that are enabled
can be reflected to the processor interrupt; disabled sources have no effect on the processor.
Returns:
None.
16.2.1.8 ROM_QEIIntEnable
Enables individual quadrature encoder interrupt sources.
Prototype:
void
ROM_QEIIntEnable(uint32_t ui32Base,
uint32_t ui32IntFlags)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_QEITABLE is an array of pointers located at ROM_APITABLE[9].
ROM_QEIIntEnable is a function pointer located at ROM_QEITABLE[11].
Parameters:
ui32Base is the base address of the quadrature encoder module.
ui32IntFlags is a bit mask of the interrupt sources to be enabled. Can be any of the
QEI_INTERROR, QEI_INTDIR, QEI_INTTIMER, or QEI_INTINDEX values.
Description:
Enables the indicated quadrature encoder interrupt sources. Only the sources that are enabled
can be reflected to the processor interrupt; disabled sources have no effect on the processor.
Returns:
None.
16.2.1.9 ROM_QEIIntStatus
Gets the current interrupt status.
Prototype:
uint32_t
ROM_QEIIntStatus(uint32_t ui32Base,
bool bMasked)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_QEITABLE is an array of pointers located at ROM_APITABLE[9].
ROM_QEIIntStatus is a function pointer located at ROM_QEITABLE[13].
Parameters:
ui32Base is the base address of the quadrature encoder module.
bMasked is false if the raw interrupt status is required and true if the masked interrupt status
is required.
