Preliminary
5.6.30.6
IRQB State Pin (IRQB STATE)—Bit 3
This read-only bit reflects the state of the external IRQB pin.
5.6.30.7
IRQA State Pin (IRQA STATE)—Bit 2
This read-only bit reflects the state of the external IRQA pin.
5.6.30.8
IRQB Edge Pin (IRQB Edg)—Bit 1
This bit controls whether the external IRQB interrupt is edge- or level-sensitive. During Stop and Wait
modes, it is automatically level-sensitive.
0 = IRQB interrupt is a low-level sensitive (default)
1 = IRQB interrupt is falling-edge sensitive.
5.6.30.9
IRQA Edge Pin (IRQA Edg)—Bit 0
This bit controls whether the external IRQA interrupt is edge- or level-sensitive. During Stop and Wait
modes, it is automatically level-sensitive.
0 = IRQA interrupt is a low-level sensitive (default)
1 = IRQA interrupt is falling-edge sensitive.
5.7 Resets
5.7.1
Reset Handshake Timing
The ITCN provides the 56800E core with a reset vector address whenever RESET is asserted. The reset
vector will be presented until the second rising clock edge after RESET is released.
5.7.2
ITCN After Reset
After reset, all of the ITCN registers are in their default states. This means all interrupts are disabled except
the core IRQs with fixed priorities:
Illegal Instruction
SW Interrupt 3
HW Stack Overflow
Misaligned Long Word Access
SW Interrupt 2
SW Interrupt 1
SW Interrupt 0
SW Interrupt LP
These interrupts are enabled at their fixed priority levels.
