I am a little confused on what I am seeing while debugging the SiLabs Board and what I witness in the Keil IDE Debugger.

(Note: Code is running fine.)

Observation 1: My code has the Crossbar set to the following:

// Configure the Crossbar and GPIO ports
//
void PORT_Init (void)
{
   XBR0    |= 0x04;                    // Enable UART0
   XBR2    |= 0x40;                    // Enable crossbar and weak pull-ups
   P0MDOUT |= 0x01;                    // enable TX0 as a push-pull output
   P1MDOUT |= 0x40;                    // enable LED as push-pull output


   P3MDOUT = 0x00;                     // P3.7 is open-drain

   P3     |= 0x80;                     // Set P3.7 latch to '1'

}
 

The Keil Debugger shows: XBRO: 0x88 XBR1: 0x88 and XBR2: 0x88

Observation 2: The UART 0 is configured for 19200 and I can communicate just fine so I know its working and configured correctly. However, the Keil debugger shows it is set to: Tx/Rx: 166666

Observation 3: While debugging, I have a switch connected to P2.0. I can Press the switch and it behaves as expected, but the Keil Debugger does NOT show any activity on this Port Bit in the debugger.

This is all very confusing to me... What am I missing here?

Thanks,

Robert
