Default Settings *)
*) Default settings: Default value means read / written values when the PON bit is set to “1” due to VDD
power-on from 0 volts.
* The day-of-week counter is incremented by 1 when the day-of-week digits are carried to the day-of-month
digits.
* Day-of-week display (incremented in septimal notation):
(W4, W2, W1) = (0, 0, 0)
→
(0, 0, 1)

…
→
(1, 1, 0)
→
(0, 0, 0)
* Correspondences between days of the week and the day-of-week digits are user-definable
(e.g. Sunday = 0, 0, 0)
* The writing of (1, 1, 1) to (W4, W2, W1) is prohibited except when days of the week are unused.
