GPIO Output channel 1. Other bits show the corresponding GPIO Output
channels. Because there are only four channels, bit 4 ~ bit 7 of *val are always
zero.
Here is an example:
If GPIO Output channel 0 and channel 2 are both 1.
unsigned char ch;
getOutChLevel( GPO0|GPO2, &ch );
The returned value of variable 'ch' is 0x5.
Return Value: If the function gets the values successfully, it returns 0. If any error, it
returns –1.

caller as an unsigned integer.
2. Syntax:
void setWtdTimer( u8 val )
Description: This function sets the watchdog timer register to the value 'val' and starts
to count down. The value could be 0 ~ 255. The unit is second. Setting the timer
register to 0 disables the watchdog function and stops the countdown.
