Delay for sampling at Ton

These bits are used to define the delay inserted before sampling in order to

sample during PWM ON time(1):

0000: Delay added to sample at TON = no delay added, sample during TOFF.

0001: Delay added to sample at TON =2.5µs

0010: Delay added to sample at TON =5µs

0011: Delay added to sample at TON =7.5µs

0100: Delay added to sample at TON = 10µs

0101: Delay added to sample at TON = 12.5µs

0110: Delay added to sample at TON = 15µs

0111: Delay added to sample at TON = 17.5µs

1000: Delay added to sample at TON = 20µs

1001: Delay added to sample at TON = 22.5µs

1010: Delay added to sample at TON = 25µs

1011: Delay added to sample at TON = 27.5µs

1100: Delay added to sample at TON = 30µs

1101: Delay added to sample at TON = 32.5µs

1110: Delay added to sample at TON = 35µs

1111: Delay added to sample at TON = 37.5µs
