Interrupt Control Register (ICR00 to ICR15)

The interrupt control register (ICR00 to ICR15) corresponds to every peripheral
function that has interrupt functions for controlling processing during interrupt
request generation. This register has different functions between write and read
operations.
I Interrupt control register (ICR00 to ICR15) function
The interrupt control register (ICR00 to ICR15) consists of bit having the following one function:
• Interrupt level setting bit (IL2 to IL0)
I Configuration of interrupt control register (ICR00 to ICR15)
When µDMA is used, the function used at a write and that used at a read are the same. When
2
EI OS is used, however, the function is different between at a write and at a read.
Figure 3.3-1 "Interrupt Control Registers (ICR00 to ICR15) during Writing" and Figure 3.3-2
"Interrupt Control Registers (ICR00 to ICR15) during Reading" shows the bit configuration of the
interrupt control register (ICR00 to ICR15).
