Chapter 7 Time Base Counter
7.2.2
Address: 0F00AH
Access: R/W
Access size: 8-bit
Initial value: 00H
LTBR is a special function register (SFR) to read the T128HZ to T1HZ outputs of the low-speed time base counter.
The T128HZ-T1HZ outputs are set to “0” when write operation is performed for LTBR. Write data is invalid.
Note:
A TBC interrupt (128Hz interrupt, 32Hz interrupt, 16Hz interrupt, or 2Hz interrupt) may occur depending on the LTBR
write timing. Take this into consideration when programming your software by referring to "Figure 7-4 Interrupt
Timing and Reset Timing by Writing to LTBR."
