LTBR is a special function register (SFR) to read the T128HZ-T1HZ outputs of the low-speed time base counter.
The T128HZ-T1HZ outputs are set to “0” when write operation is performed for LTBR.
Note:
A TBC interrupt (128Hz interrupt, 64Hz interrupt, 32Hz interrupt, 16Hz interrupt, 8Hz interrupt, 4Hz interrupt, 2Hz
interrupt, or 1Hz interrupt) may occur depending on the LTBR write timing (see Figure 7-4, “Interrupt Timing and
Reset Timing by Writing to LTBR”). Therefore, take care in software programming.
