RM48L530: RM48L530

Part Number:RM48L530

Dear sir / madam,

I would be very grateful if you could check the circuit attached regarding the Oscillator and JTAG interface.

The 2 things I am unsure of are:

1. OSCILLATOR:
   1. The oscillator we are using is an oscillator module (i.e. for better reliability) which has a single output which I have connected to OSCIN. Thus OSCOUT and KELVIN-GND are unconnected.
   2. We are using a 5V oscillator output which step down to 3.3V level using a potential divider (this has worked ok before on a PIC 3V3 micro)/
2. JTAG INTERFACE
   1. The reset from the JTAG device is connected to the warm reset (nRST) of the micro is that correct?
   2. On other micro's we have connected this to the reset pin as there is usually only one. In this case could it be connected to the power on reset (nPORRST)?

p.s. I have based the design on the RM48 HDK development board.

Many thanks

Brendan Johnson
