Clock/calendar with Power Fail Detector
PCF8573
Acknowledgement response of the PCF8573 as slave-receiver is shown in Table 6. Note that data is only associated
with the ‘execute address’ function where C0, C1, C2 = 0, 0, 0.
Table 6
Slave receiver acknowledgement; note 1
Note
1.
‘X’ is ‘don’t care’.
To read the addressed part of the time counter and alarm register, plus information from specified control/status flags,
the BCD digits in the DATA byte are organized as shown in Table 7.
The status of the CONTROL-nibble of the MODE-POINTER-WORD (C2, C1, C0) remains unchanged until re-written.
Table 7
Organization of the BCD digits in the DATA byte; note 1

‘D’ is the data bit; ‘m’ = minutes; ‘s’ = seconds.
