2. Next, enable the USB and the DCD clock gating bits in the SIM.
3. Pre-initialize the USB. This is required to enable the pullup resistor that is controlled
4. Configure the DCD clock register.
5. At this point the application is polling the PTB0 pin for VBUS detection, but a port
6. Finally, when the detection sequence is completed the application needs to read the

u8ChargerType = (UINT8)((USBDCD_STATUS & USBDCD_STATUS_SEQ_RES_MASK)>>16);
u8ChargerType|= (UINT8)((USBDCD_STATUS & USBDCD_STATUS_FLAGS_MASK)>>16);
return(u8ChargerType);
