With this register set, an interrupt driver can set the SIM_ISALL register pair to point to its peripheral
registers and then use the I/O Short addressing mode to reference them. The ISR should restore this register
to its previous contents prior to returning from interrupt.

The default value of this register set points to the EOnCE registers.
The pipeline delay between setting this register set and using short I/O addressing with the new value
is five cycles.
