SS
pin, it is 03

at a reset.

: This bit is the cold start / warm start flag, is set to “0” at power on reset (refer to Page 71).
: 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.
