Each pin except BKGD can act as general purpose I/O. In addition each pin can act as an output or input
of a peripheral module.

Address 0x029F
When change SRRV from non-zero value to zero value or vice versa, It will need to wait about 300 nanoseconds delay before
the slew rate control to be real function as setting. When enter STOP, to save the power, the slew rate control will be force to off
state. After wakeup from STOP, it will also need to wait about 300 nanoseconds before slew rate control to be function as setting.
When MC function is disabled and IIC/SPI/PWM async shutdown are routing to PV and enabled, the corresponding digital input
buffer will be always enabled
