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.

Note:
6.5.10.1
This field represents the upper two address bits of the “hard coded” I/O short address.
6.5.10.2
This field represents the lower 16 address bits of the “hard coded” I/O short address.
6.5.11
The Peripheral Clock Enable Register 2 is used to enable or disable clocks to the peripherals as a
power-saving feaure. The clocks can be individually controller for each peripheral on the chip.
6.5.11.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.

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 three cycles.
