Notes: 1. For details of MSTPCR0 and MSTPCR1, see figure 15.1.

2. The initial value after a power-on reset depends on the combination of mode pin states

(MODE11 and MODE12).

If a low level signal is input to the MODE12 pin, the initial value is H'0010 0000.

If a high level signal is input to the MODE12 pin and a low level signal is input to
MODE11, the initial value is H'0030 0000.

If a high level signal is input to the MODE12 and MODE11 pins, the initial value is
H'0020 0000.
