With this register set, an interrupt driver can set the SIM_IOSALO 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.

Note:
6.3.10.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
6.3.10.2
This field represents the upper two address bits of the “hard coded” I/O short address.

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 instruction cycles.
