CHAPTER 3 INTERRUPT
3.3.1
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.
■
Interrupt control register (ICR00 to ICR15) function
The interrupt control register (ICR00 to ICR15) consists of bit having the following four functions:
•
Interrupt level setting bit (IL2 to IL0)
•
Extended intelligent I/O service (EI
2
OS) permission bit (ISE3)
•
Extended intelligent I/O service (EI
2
OS) channel selection bits (ICS3 to ICS0)
•
Extended intelligent I/O service (EI
2
OS) status bits (S1, S0)
■
Configuration of interrupt control register (ICR00 to ICR15)
Figure 3.3-1 shows the bit configuration of the interrupt control register (ICR00 to ICR15).
Figure 3.3-1 Bit configuration of interrupt control register (ICR00 to ICR15)
Notes:
• Only when extended intelligent I/O service (EI
2
OS) is started, the ICS3 to ICS0 bits are valid.
Please set "1" to the ISE bit when EI
2
OS is started. Please set "0" to the ISE bit when EI
2
OS is
not started. When EI
2
OS is not started, the setting of the ICS3 to ICS0 bits are unnecessary.
• ICS1, ICS0 bits can be only write. S1, S0 bits can be only read.
