Hibernation RTC Sub Seconds (HIBRTCSS)
This register contains the RTC sub seconds counter and match values. The RTC value can be read by first reading the HIBRTCC register, reading the RTCSSC field in the HIBRTCSS register, and then rereading the HIBRTCC register. If the two values for HIBRTCC are equal, the read is valid.
NOTE
Except for the HIBIO and a portion of the HIBIC register, all other Hibernation module registers are on the Hibernation module clock domain and have special timing requirements. Software should make use of the WRC bit in the HIBCTL register to ensure that the required timing gap has elapsed. If the WRC bit is clear, any attempted write access is ignored. See Section 6.3.1. The HIBIO register and bits RSTWK, PADIOWK and WC of the HIBIC register do not require waiting for write to complete. Because these registers are clocked by the system clock, writes to these registers/bits are immediate.
Writing to registers other than the HIBCTL and HIBIM before the CLK32EN bit in the HIBCTL register has been set may produce unexpected results.
NOTE
There is a minimum system clock rate of three times the HIB clock rate to properly read the HIBRTCSS register.
HIBRTCSS is shown in Figure 6-18 and described in Table 6-13.
