Mn16CTON: 16-bit C/F counter control
D6: This bit must be cleared to zero.
MnST: Time slot counter start control
When this bit changes from low to high the time slot counter will be enabled and the
touch sense procedure started. When the time slot counter has completed its counting an
interrupt will be generated.
MnROEN: Reference clock control
MnRCCLR: Time slot counter clear control
This bit must be first set to 1 and then to 0.
Mn16CTCLR: 16-bit C/F counter clear control
This bit must be first set to 1 and then to 0.
D1: This bit must be cleared to zero.
MnROS: Time slot counter clock source
M0:K4, M1:K8, M2:K12, M3:K16, M4:K20
D7, D6: Read only bits -- unknown values
MnRCOV: Time slot counter overflow flag
Mn16CTOV: 16-bit C/F counter overflow flag
D3: This bit must be cleared to zero.
