(1) All peripheral clocks (except CPU timer clocks) are disabled upon

reset. Writing to or reading from peripheral registers is possible only

after the peripheral clocks are turned on.

(2) Operating the XINTF bus has a significant effect on IDDIO current. It

will increase considerably based on the following:

• How many address/data pins toggle from one cycle to another

• How fast they toggle

• Whether 16-bit or 32-bit interface is used and

• The load on these pins.

• Whether internal pullups are enabled on the XINTF pins.
