RTC Phase Adjustment Register - 9.0 English

The following table describes the Phase Adjustment Register that has units of nanoseconds. This value is added to the synchronized value of the RTC nanoseconds field, and the RTC timing signals are then derived from the result. This phase offset is therefore applied to the clk8k signal. As an example, writing the value of the decimal 62500 (half of an 8 kHz clock period) to this register would invert the clk8k signal with respect to a value of 0. Therefore, this register can provide fine grained phase alignment of these signals to a 1 ns resolution.
