Chapter 6. QMC Initialization
A typical setting would be:
GSMR_H = 0x0000_0780;
/* enable pulse mode and sampling */
Step 10. Initialize general SCCx mode reg low, GSMR_L (see Table 6-5). For more
information on GSMR programming, see page 7-111 of the MC68360 User’s Manual and
page 16-153 of the MPC860 User’s Manual.
