CHAPTER 7: SUMMARY OF NOTES
(5) To reduce current consumption, be careful not to set the
heavy load protection mode with the software unless
otherwise necessary.
When BZ has been selected by the output application for pin
R13, the mask option decides whether output is controlled
by register R13, or by register R10 simultaneously with BZ.
In particular, when BZ output is under R10 control, register
R13 can be used as a 1-bit general register for read/write.
Data in this register has no affect on BZ output (output of
pin R13).
(1) When 40H–6FH is selected for the segment data memory,
the memory data and the display will not match until the
area is initialized (through, for instance, memory clear
processing by the CPU).
Initialize the segment data memory by executing initial
processing.
(2) When C0H–EFH is selected for the segment data memory,
that area becomes write-only. Consequently, data cannot
be rewritten by arithmetic operations (such as AND, OR,
ADD, SUB).
(3) Data output from segment pins selected as DC output
will be the data corresponding to the COM0 pins.
(4) When performing step adjustment with the static drive,
set the segment data so that all LCD segments are lit.
(1) When the clock timer has been reset, the interrupt factor
flag (TI) may sometimes be set to "1". Consequently,
perform flag read-out (reset the flag) when necessary at
reset.
(2) The watchdog timer may be counted up at clock timer
reset.
(3) Resetting the clock timer has no effect on the stopwatch
counter, and vice versa.
(4) Writing to the interrupt mask register (ETI) can be done
only in the DI status (interrupt flag = "0"). Writing during
EI status will cause an error.
