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, 32Hz interrupt, 16Hz interrupt, or 2Hz 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.
(*) In the case of ML610Q415, the frequency will be {122Hz , 30.5Hz , 15.3Hz , and 1.9Hz} ± temperature variation
of RC oscillation.
