27.6.3.4 QEI Interrupt Enable register
27.6.3.5 QEI Interrupt Clear register
This register enables interrupt sources. Bits set to 1 enable the corresponding interrupt; a
0 bit disables the corresponding interrupt.
Writing a 1 to a bit in this register clears the corresponding bit in the QEI Interrupt Status
register (QEISTAT).
Indicates that a velocity timer overflow occurred
Indicates that captured velocity is less than compare velocity.
Indicates that the position 0 compare value is equal to the current position.
Indicates that the position 1compare value is equal to the current position.
Indicates that the position 2 compare value is equal to the current position.
Description
Indicates that an index pulse was detected.
Indicates that a change of direction was detected.
Indicates that an encoder phase error was detected.
Indicates that and encoder clock pulse was detected.
Indicates that the index compare value is equal to the current index count.
