Preliminary Specification
This is a preliminary specification and is subject to change.
6. Resets
6.4 Operations
6.4.1 Status After Reset
The status of SFRs after reset depends on the reset type. Refer to values after reset in 4. “Special
Function Registers (SFRs)”. Table 6.6 lists Pin Status When RESET Pin Level is Low, Figure 6.2 shows
CPU Register Status after Reset, and Figure 6.3 shows Reset Sequence.

Notes:
1. These two columns show the valid pin state when the internal power supply voltage has stabilized
after power on. The pin state is undefined until the internal power supply voltage stabilizes.
2. Input a high-level signal.
3. Input a low-level signal.
