SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Reset

Figure 1.5.3. 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 1: When the V
CC
level is applied to the CNV
SS
pin, it is 03
16
at a reset.
Note 2: “00
16
” is read out when set bit 7 (SDDS) of the UART2 special mode register ( address 0377
16
) to “1”.
