The priority level which is automatically assigned when the IPSETE bit is 1 differs according to
the interrupt control mode.
In interrupt control mode 0, the I bit in CCR of the CPU is reflected in bit CPUP2. Bits CPUP1
and CPUP0 are fixed 0. In interrupt control mode 2, the values of bits I2 to I0 in EXR of the CPU
are reflected in bits CPUP2 to CPUP0.
Table 6.7 shows the CPU priority control.
