5.6.30.4
This bit allows all interrupts to be disabled.
5.6.30.5
This bit field is reserved or not implemented. It is read as 1 and cannot be modified by writing.
5.6.30.6
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.30.7
This read-only bit reflects the state of the external IRQA pin.
5.6.30.8
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.30.9
This bit controls whether the external IRQA interrupt is edge- or level-sensitive. During Stop and Wait
modes, it is automatically level-sensitive.
5.7 Resets
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.
5.7.2
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
These interrupts are enabled at their fixed priority levels.
