Section 7 Interrupt Controller
the condition that has held the activation source is cancelled (CPUPCE = 1 and the value of the
bits CPUP2 to CPUP0 is greater than that of the bits EDMAP2 to EDMAP0). When different
priority level is assigned for each channel, channels having higher priority than CPU continue
transferring processing, while activation sources for channels with lower priority should only be
held.
There are two methods for assigning the priority level to the CPU by the IPSETE bit in CPUPCR.
Setting the IPSETE bit to 1 enables a function to automatically assign the value of the interrupt
mask bit of the CPU to the CPU priority level. Clearing the IPSETE bit to 0 disables the function
to automatically assign the priority level. Therefore, the priority level is assigned directly by
software rewriting bits CPUP2 to CPUP0. Even if the IPSETE bit is 1, the priority level of the
CPU is software assignable by rewriting the interrupt mask bit of the CPU (I bit in CCR or I2 to I0
bits in EXR).
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 7.7 shows the CPU priority control.
