Functional Description
2.4.1
General
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.
2.4.2
Registers
lists the configuration registers which are available on each port. These registers except the pin
input registers can be written at any time, however a specific configuration might not become active.
For example selecting a pullup device: This device does not become active while the port is used as a push-
pull output.
1. When change SRRx 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. To enable the TIM0 ICx functions which shared with motor pads, the corresponding SRRx bit
should be set to zero.
