• Manufacturer Part Number: r8a77850anbg
• Description: Renesas 32-bit Risc Microcomputer Superh? Risc Engine Family
• Manufacturer: Renesas Electronics Corporation.

If the interrupt source in an individual module is set or cleared, the time required until the state is
reflected in INT2A1 is as shown in table 10.7.
If the interrupt masking is set by INT2MSKR or the interrupt masking by INT2MSKR is cleared
by INT2MSKCLR, the reflection time required for INT2A1 is guaranteed by hardware. Therefore,
after the interrupt mask is set or cleared, the contents that reflect the setting of INT2MSKR can be
read.

Description
These bits indicate the interrupt
source of each peripheral module
that is generating an interrupt.
(INT2A1 is affected by the setting
of the interrupt mask register).
0: No interrupt
1: An interrupt has occurred
Note: Interrupt sources can also
be identified by directly
reading the INTEVT code.
In this case, reading from
this register is not required.
