27.6.2.16 QEI Index acceptance window register
27.6.2.17 QEI Index Compare register 1
27.6.2.18 QEI Index Compare register 2
This register contains the width of the index acceptance window, when the index and the
phase / clock edges fall nearly together. If the activating phase / clock edge falls before
the Index, but within the window, the (re)calibration will be activated on that clock/phase
edge.
Table 593. QEI Index acceptance window register (WINDOW - 0x400C 6048) bit description
This register contains an index compare value. This value is compared against the current
value of the index count register. Interrupts can be enabled to interrupt when the compare
value is less than, equal to, or greater than the current value of the index count register.
Table 594. QEI Index Compare register 1 (INXCMP1 - address 0x400C 604C) bit description
This register contains an index compare value. This value is compared against the current
value of the index count register. Interrupts can be enabled to interrupt when the compare
value is less than, equal to, or greater than the current value of the index count register.
