5.6.30.4 Interrupt Disable (INT_DIS)—Bit 5
This bit allows all interrupts to be disabled.
0 = Normal operation (default)
1 = All interrupts disabled
5.6.30.5 Reserved—Bit 4
This bit field is reserved or not implemented. It is read as 1 and cannot be modified by writing.
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

5.7.1
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.
