THE SPH1A1 REGISTER IS USED TO SET THE SPECIAL H1A PATTERN IN THIS REGION.
THE SPH1A2 REGISTER IS USED TO SET THE SPECIAL H1A PATTERN IN THIS REGION.
THE SPH1A3 REGISTER IS USED TO SET THE SPECIAL H1A PATTERN IN THIS REGION.
SPHSTART0 IS USED WHEN THE LM0 PULSE IS SELECTED BY SETTING LMPATSEL = 0.
SPHSTART1 IS USED WHEN THE LM1 PULSE IS SELECTED BY SETTING LMPATSEL = 1.
