5.8 Clocks
The EMI operates from clocks internal to the chip and does not require/provide clocks external to the chip.
5.9 Interrupts
There are no interrupts generated by this module.
5.10 Resets
All reset types are equivalent for the EMI and therefore have the same effect. The EMI outputs during reset are controlled by the DRV bit of the BCR. During reset this bit is set to zero. Therefore, Table 5-6 defines the reset state of all EMI pins.
