Note:
Nested interrupts may cause this field to be updated before the original interrupt service routine can
read it.
5.5.16.4
Interrupt Disable (INT_DIS)—Bit 5
This bit allows all interrupts to be disabled.
0 = Normal operation (default)
1 = All interrupts disabled
5.5.16.5
Reserved—Bits 4–2
This bit field is reserved or not implemented. It is read as 1 and cannot be modified by writing.
5.5.16.6
Reserved—Bits 1–0
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.

Description of Reset Operation
5.6.2.1
Reset Handshake Timing
The ITCN provides the 56800E core with a reset vector address on the VAB pins whenever RESET is
asserted from the SIM. The reset vector will be presented until the second rising clock edge after RESET
is released. The general timing is shown in Figure 5-19.
