R/W Removal of Split-Resistance Control
CDS2
CDS1
CDS0
These bits control whether the split-resistance is removed
or connected.
CDS3 = 0, CDS2 = CDS1 = CDS0 = 1: Split-resistance
removed
All other settings: Split-resistance connected
Note: * Applies to H8/38104 Group only. On the H8/3802 Group, H8/38004 Group or H8/38002S
Group, these bits are reserved like bit 4.
