How to simulate SN8P2308 RFC function?
When users develop product using 2308 RFC function, because there is no RFC function
built in simulator, so user must use 2308 EV_Kit, the following is 2308 EV Kit picture:
The blue circles shown in the EV board above is the interface for RFC connected with target board, if short the corresponding channel, RFC output signal can be obtained in CON2, users can connect the target board to CON2 for RFC simulation. In addition, JP3 can be used as RFC output clock measuring points besides connecting EV-Kit and target board, In development, we can determine the frequency by measuring the corresponding channel, according to this value, user can choose frequency measurement or pulse width measurement. When simulate RFC function, users must use RFC 2308 EV_Kit to go with the simulator as the simulator itself without RFC function.
The red circle in the above table is for RFC circuit, C11, C12, C13 are oscillator capacitors for the RFC circuit, in simulation, user only need to plug capacitor in one of them, R3, R4, R5 are oscillator resistances for the RFC circuit, in which R3 is connected to RFC0 channel, R4 for RFC1 channel, R5 for RFC2 channel. Before RFC enabled, P5.0~P5.3 must be set as input mode without pull-up resistor first by program.
