* At this point, the new bytes are transferred to the A registers of both devices and stored. Additionally, for both devices, the
13 LSBs in each of the first buffers of the R registers are transferred to the respective R register’s second buffer. Thus, the
R, N, and A counter can be presented new divide ratios at the same time. The first buffer of each R register is not affected.
Neither C register is affected.
