I am using a dspic30f4011 controller. I am confused about the oscillator frequency. According to the datasheet, it can support 4 to 10 MHZ. I have 8 MHZ and 11.0529 M HZ crystal oscillator. I know, there are two types of the external oscillator can be connected to the controller. 1. XT which is up to 4 MHZ and other is 4 MHZ to 10 MHZ which is HS type oscillator. I am using this oscillator with dspic30f4011. I don't know this type. It might be HS type as it is with high frequency.
But the problem is that I am not using the external oscillator below 10 MHZ. If I used 110.592 MHZ oscillator, What will happen? should I have to use exact value of external oscillator?
define FCY 18000000 //
define FPWM 4000 //
define DEADTIME (unsigned int)(0.00004* FCY)
define FOSC 11052900 //64MHZ
can you tell me what I have to configure about FCY, FOSC for this crystal oscillator for dspic30f4011?
I am very sorry for this question but I am confused with much more information on the internet.
