Notes: 1. When watch mode or subactive mode on HD404829R Series/HD4074829 is used and the LCD
function is off in that mode, the watch mode or subactive mode current is larger, and
consequently the following settings should be made.
Perform the following writes in the order shown before the transition to watch mode (before
execution of the STOP instruction):
Write $0 to LCR
Write $3 to LMR
Also, when returning to active mode from watch mode or subactive mode, perform the following
writes in the order shown:
Write a value appropriate to the conditions of use to LMR
Write a value appropriate to the conditions of use to LCR
A sample programming flowchart for the above procedures is shown in figure 23.
