Figure 1.4.3. Device's internal status after a reset is cleared
x : Nothing is mapped to this bit
: Undefined
The content of other registers and RAM is undefined when the microcomputer is reset. The initial values
must therefore be set.
Note: When the V
CC
level is applied to the CNV
SS
pin, it is 03
16
at a reset.
