The global utilities block controls power management, I/O device
|
||
|
|
enabling, power-on-reset configuration monitoring, general-purpose
|
||
|
|
I/O signal configuration, alternate function selection for multiplexed
|
||
|
|
signals, and clock control.
|
||
|
|
|
||
|
|
Required properties:
|
||

|
||
|
|

|
||
|
|
