The following table describes the nanoseconds field value register for the nanoseconds field of the RTV. When read, this returns the latest value of the counter. The registers defined in this section are linked. When this nanoseconds value register is read, the entire RTC (including the seconds field) is sampled.
Bits | Default Value | Type | Description |
---|---|---|---|
31:30 | 0 | RO | Reserved |
29:0 | 0 | RO |
Current Value of the synchronized RTC nanoseconds field. Note: A read from this register samples the entire RTC counter
(synchronized) so that the Epoch and Seconds field are held static for a
subsequent read.

The following table describes the lower 32 bits of the seconds value register for the seconds field of the RTC. When read, this returns the latest value of the counter. The registers defined in this section are linked. When the nanoseconds value register is read (see Table 1), the entire RTC is sampled.
Bits | Default Value | Type | Description |
---|---|---|---|
31:0 | 0 | RO | Sampled Value of the synchronized RTC Seconds field (Bits[31:0]). |
The following table describes the upper 16 bits of the seconds value register for the seconds field of the RTC. When read, this returns the latest value of the counter. The registers defined in this section are linked. When the nanoseconds value register is read (see Table 1), the entire RTC is sampled.
Bits | Default Value | Type | Description |
---|---|---|---|
31:16 | 0 | RO | Reserved |
15:0 | 0 | RO | Sampled Value of the synchronized RTC Seconds field (Bits[47:32]). |
