(3) Sub-count register (SUBC)
(4) Second count register (SEC)
(5) Second count setting register (SECB)
The SUBC register is a 15-bit register that counts the reference time of the real-time counter. It counts 1
second using the 32.768 kHz clock. This register is read-only, in 16-bit or 8-bit units.
This register is not initialized after reset or when RTCE = 0.
This 8-bit register uses a value of 0 to 59 (decimal) to indicate the count value in seconds. This register is
read-only, in 8-bit units.
This register is not initialized after reset or when RTCE = 0.
This is an 8-bit register for setting the second count. This register is read-only, in 8-bit units. Set a count value
in a range of 0 to 59 (decimal) to this register. Do not set a count value of 60 (decimal) or greater.
This register is cleared to 00H after reset.
