Note:
  1. The AOHPR, AOHPM and AOHPL pins are not available in the IS2083BM-2L2 variant as it does not support an analog output from the internal DAC.
  2. The conventions used in the preceding table are indicated as follows:
    • I = Input pin
    • O = Output pin
    • I/O = Input/Output pin
    • P = Power pin
