Interrupt Request Register 2 (IRR2)
Note: * Only a write of 0 for flag clearing is possible.
IRR2 is an 8-bit read/write register, in which the corresponding bit is set to 1 when a direct
transfer, A/D converter, SCI2, timer G, timer FH, timer FL, timer C, or timer B interrupt is
requested. The flags are not cleared automatically when an interrupt is accepted. It is necessary to
write 0 to clear each flag.
