}
This array contains the sine table offset that corresponds to the hall sensor values when running in the forward direction. At the moment of a hall change, using the new hall sensor value as index into this table returns the sine table offset that will synchronize the generated sine waves to the back-EMF of the motor.

Initial value:
{
0xff, 3, 6, 2, 5, 1, 4, 0xff
}
This array contains the next expected hall sensor value when running in the forward direction. The value at the index pointed to by the current hall sensor value is the next expected hall sensor value in the forward direction.

Sine wave modulation table.
Table containing modulation values for all three phases. The table is organized as [U1, V1, W1, U2, V2, W2, ...] for forward driving, and [U1, W1, V1, U2, W2, V2, ...] for reverse driving.
