FUNCTIONAL DESCRIPTION
Register Tables
Bank 0 (clock, calendar registers)
Bank 1 (alarm, FOUT registers)
Bank 2 (digital correction, timer registers)
I
All bits in register F and bits 2 to 3 in register E
are common to all register banks.
I
When alarm interrupts are not used, registers 0 to
8 in bank 1 can be used as RAM (total 36 bits).
I
When timer interrupts are not used, registers 4 to 5
in bank 2 can be used as RAM (total 8 bits).
I
When digital correction is not used, registers 0 to
1 in bank 2 can be used as RAM, excluding bit 3
(DT_ON) in register 1 (total 7 bits).
I
The BUSY/ADJ bit function is BUSY when read-
ing, and ADJ when writing.
I
The BUSY flag is set to 1 an interval of 244μs
before clock counter update timing.
I
Registers 6 and 7 in bank 2 are read-only registers,
and cannot be written to.
I
When power is applied, all register bits are unde-
fined, with the exception of bits FOS, TEST and
TEMP. Accordingly, these bits need to be initial-
ized. TEST and TEMP are automatically reset to 0
and FOS is automatically reset to 1 when power is
applied.
I
Bits marked # are all read-only bits fixed to 0.
These bits cannot be written to.
I
Bits marked * can be used as RAM bits.
