Interrupt Source
SFR Definition 9.7. SWCINT: Software Controlled Interrupt Register
SCI3: Software Controlled Interrupt 3 Bit.
If enabled, writing a logic 1 to this interrupt control bit will cause the CPU to vector to the
SCI3 interrupt service routine. This bit is not cleared in hardware. It must be cleared by
software.
SCI2: Software Controlled Interrupt 2 Bit.
If enabled, writing a logic 1 to this interrupt control bit will cause the CPU to vector to the
SCI2 interrupt service routine. This bit is not cleared in hardware. It must be cleared by
software.
SCI1: Software Controlled Interrupt 1 Bit.
If enabled, writing a logic 1 to this interrupt control bit will cause the CPU to vector to the
SCI1 interrupt service routine. This bit is not cleared in hardware. It must be cleared by
software.
SCI0: Software Controlled Interrupt 0 Bit.
If enabled, writing a logic 1 to this interrupt control bit will cause the CPU to vector to the
SCI0 interrupt service routine. This bit is not cleared in hardware. It must be cleared by
software.
