* Function		: MN_CtDemoCase11
* Description	: Use CT16B2 to demo PWM output with Dead-band function. 
*							  The total PWM period 1ms@HCLK = 12MHz is determined by MR9 setting with 12000.
*               And PWM0/PWM1/PWM2 has the duty of 10%, 30%, and 75% respectively.
*								PWM0N/PWM1N/PWM2N/PWM3N pins will output to P1.0, P1.3, P0.3 and P3.9.
*								User can observe the PWMxN waveforms on those I/O pins.
*								Also, demo case will toggle P1.0 in main loop once MR9 match interrupt occurs. 
* Input			: None
