Changes from TLE8242L Rev 1.0 datasheet
Section 1.3.2, equation for duty-cycle: revised equation to include the M variable.
M is the # of ADC samples per PWM period. revised equation for calculating the
duration of the autozero procedure
Section 5.3, added new filter times to table 2
Section 5.3.2, electrical table, parameters 5.3.12 through 5.3.15 revised with new
filter times
Section 5.9.2.1, revised IC version number
Section 5.9.2.2, added new filter times.
Section 5.9.2.14, added equations for current feedback value when dither is
disabled
Section 5.9.2.14, added equation for autozero offset value
Section 5.9.2.7 and 5.9.2.8, added note that a pulse is needed on the phase_sync
pin to synchronize the channels after exiting the reset state.
Section 5.7.1, added maximum value of analog to digital converter sample rate
Section 5.2, added note that a pulse is needed on the PHASE_SYNC pin in order
to synchronize the PWM periods of the channels after exiting the reset state
