(1) DPWM outputs are low after reset. Other GPIO pins are configured as inputs after reset.
(2) On the 40 pin package V33DIO is connected to V33D internally.
(3) The maximum total current, IOHmax and IOLmax for all outputs combined, should not exceed 12 mA to hold the maximum voltage drop specified. Maximum sink current per pin = –6 mA at VOL; maximum source current per pin = 6 mA at VOH.
(4) Time from close of error ADC sample window to time when digitally calculated control effort (duty cycle) is available. This delay, which has no variation associated with it, must be accounted for when calculating the system dynamic response.
(5) Characterized by design and not production tested.
(6) Ambient temperature offset value should be used from the TEMPSENCTRL register to meet accuracy.
(7) Available from reference DACs for comparators D, E, F and G.
