NOTES:
1) For compatibility with the MC68HC912DG128, CA, CB, CC bits must be ‘0’ where masked on the
MC68HC912DG128. This is shown above in bold text.
2) When MULT = 0, all four bits (SC, CC, CB, and CA) must be specified and a conversion sequence consists of four
or eight consecutive conversions of the single specified channel.
3) When S8C = 0 and S1C = 1, all four bits (SC, CC, CB, and CA) must be specified and a conversion sequence consists
of one conversion of the single specified channel.
