Inverts the polarity of the pulse outputs. Normally, these pulses are active low. When
inverted, they become active high.
Indicates that the preboot sequence is active.
RTC adjust. See Section
PREG[16:0] and QREG[1:0] are separate in hardware but can be programmed with a
single number calculated by the MPU.
The duration of the pre-summer, in samples.
RTC adjust. See Section
The sub-second counter is restarted when a 1 is written to this bit.
Analog RTC adjust. See Section
These are the year, month, day, hour, minute and second parameters of the RTC.
Writing to these registers sets the time. Each write operation to one of these registers
must be preceded by a write to 0x201F (WE). Valid values for each parameter are:
Values in the RTC registers are undefined when the IC powers up without a battery but
are maintained through mission and battery modes when a sufficient voltage is maintained
at the VBAT pin.
* no change of value at reset.
Real Time Monitor (RTM) enable. When 0, the RTM output is low.
The four RTM probes. Before each CE code pass, the values of these registers are
serially output on the RTM pin. The RTM registers are ignored when RTM_E = 0.
