PCF8563
Now we just check and compare with a PCF8563 data sheet and real register value.
but our real 01h value and a data sheet value is different
our register value
01h - 0x80 , 0xC0
on data sheet
01h - N (0x00)
we compare with a TABLE 4. Formatted registers overview
can you check that problem please?
Solved! Go to Solution.
can you catch the waveform using oscilloscope to show each bit value for your read command?

other reset register value is same all right but 01h reset register value is different with a data sheet
