6.11Oversampling
Encoder signal oversampling optimizes the accuracy of resolver and SinCos
signals. This function can only be used, if necessary, for low-track SinCos encoders
and resolvers; using it for high-track SinCos encoders is not permissible.

By way of parameters P548[0] - ENC_CH1_MTEnable = 1 (for Channel 1) and
P585[0] - ENC_CH3_MTEnable = 1 (for Channel 3) a multi-turn encoder can be run
as a single-turn encoder. This function is used primarily for testing purposes.
