Table 5-3
Note: * Reserved bits. These bits cannot be modified and are always read as 1.
As shown in table 5-3, multiple interrupts are assigned to one IPR. Setting a value in the range from H'0 to H'7 in the 3-bit
groups of bits 6 to 4 and 2 to 0 sets the priority of the corresponding interrupt. The lowest priority level, level 0, is
assigned by setting H'0, and the highest priority level, level 7, by setting H'7.
When interrupt requests are generated, the highest-priority interrupt according to the priority levels set in the IPR registers
is selected. This interrupt level is then compared with the interrupt mask level set by the interrupt mask bits (I2 to I0) in
the extend register (EXR) in the CPU, and if the priority level of the interrupt is higher than the set mask level, an interrupt
request is issued to the CPU.
5.2.3
IER is an 8-bit readable/writable register that controls enabling and disabling of interrupt requests IRQ7 to IRQ0.
IER is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 to 0—IRQ7 to IRQ0 Enable (IRQ7E to IRQ0E): These bits select whether IRQ7 to IRQ0 are enabled or
disabled.
