13.4.3

Reading the Time

Figure 13.3 shows how to read the time. If a carry occurs while reading the time, the correct time
will not be obtained, so it must be read again. Part (a) in figure 13.3 shows the method of reading
the time without using interrupts; part (b) in figure 13.3 shows the method using carry interrupts.
To keep programming simple, method (a) should normally be used.

Write 0 to CF in RCR1
Note: Set AF in RCR1 to 1 so that
alarm flag is not cleared.

Write 0 to CIE in RCR1

Read RCR1 and check CF

Write 0 to CIE in RCR1

Carry flag = 1?

No

Yes

Clear the carry flag

Disable the carry

Write 1 to CIE in RCR1,
and write 0 to CF in RCR1
Note: Set AF in RCR1 to 1 so that
alarm flag is not cleared.
