15. Module: QEI

When QEI is configured in Quadrature mode (CCM[1:0] = 0b00) with PIMOD[2:0] = 0b001, any index event is supposed to reset the position counter. However, an index event will not reset the position counter; instead, it will be loaded with 0x00000001.

Work around

The user application can enable an interrupt on the index event and load the position counter with zero. The index event should be sufficiently large enough to allow the software to reset the position counter before the next count-up or count-down pulse.
