7.2.4 Simplified RTC Time Base Counter register (LTBRR)
The low speed time base counter register for Simplified RTC(LTBRR) is a specific function register (SFR) to read the
counter value for the Simplified RTC.
If the write-operation is performed onto the LTBRR, the all bits T128HZ to T1Hz are initialized to "0".
LTBRR is also initialized to "0x00" at the Power-On-Reset.
This register is available on the ML62Q1500 and ML62Q1700 group.
Address:
0xF064 (LTBRR)
Access:
R/W
Access size: 8 bit
Initial value: 0x00

[Note]
Ÿ
LTBRR register is uninitialized exept for the Power-On-Reset. Initialize by writing arbitrary data if
needed.
Ÿ
The simplified RTC interrupt may occur depending on a write timing to the LTBRR. Do not perform the
write operation to the LTBRR while the simplified RTC is running.
Ÿ
When the high-speed clock is used for the system clock, read the LTBRR register twice to verify the data
to prevent reading uncertain data while counting-up.
