SCFC1 - SSCG frequency control register 1
The 8-bit SCFC1 register controls the frequency multiplication of the SSCG. It
determines the SSCG output frequency and is used in conjunction with
register SCFC0.
The center SSCG output frequency is f
SSCGc
= (4 MHz
×
N/M) / 2. This
register defines the factor “n” and thus N = n + 1.
Access
This register can be read/written in 8-bit or 1-bit units.
