ADuC7060 Datasheet clarification

Answering my own question, 31:24 are bits 31 to 24, bits 23 to 16, etc.. I saw in another place with the bit map, and voila, I understood the meaning. It would be very useful if the DS were not so summarized...

Still trying to find the answers for the other ones.

Hi,

For the IRQEN, your right BIT4 + BIT13 is 0x2010. On page 60, Table 65, the IRQ/FIQ MMR Bit Designations show that Bit 4 is designated for the Timer 1 or wake-up timer. Setting a bit to 1 in IRQEN enables the corresponding source request.

GP1DAT is for the data registers of Port 1. In Table 114, setting the bit to 1 configures the GPIO pin as output. Bit 31:24 represents a pin for the port, Bit 24 is for pin 0, while Bit 30 is for pin 6.

You can use a USB adapter with the RS232 and a hyperlink terminal. The RS232 headers in the eval board are connected to the UART pins of ADuC7060.

Hi Karl,

Thanks a lot for getting back to me. It is little more clear now, but I am still struggling a bit how the C language is applied to this microcontroller... So, I guess when one is doing BIT4 + BIT13, it is setting bit 4 and bit 13 for IRQEN. For instance, on page 35 IRQEN is enabling timer 1 in a total different way. The documentation is incomplete and so far I cannot find a suitable source that explains these things.

Take care,

Carlos

Hi Carlos,

You only need to set Bit 4 for IRQEN to enable timer 1. Setting Bit 13 for IRQEN enables the external interrupt 0.

Hi Karl,

But then, what is the meaning of having expressions like this:

IRQEN = BIT4 + BIT13; //

GP1DAT  = BIT30;        //

Do you know where I can find detailed information how write these statements?

Thank you,

Carlos

Hi,

The expressions are a method of setting the bits of a particular register.

In the IRQEN expression, if you only need to use the timer 1 interrupt, you only need to set Bit 4 of IRQEN to 1. Bit 13 is set to 1 if you need an external interrupt source.

The data sheet has information on what happens if you set or clear a particular bit in a register.

I have attached some examples of using the different peripherals of the board. This may help you in your application.

Hi Karl,

Thanks a lot for getting back to me. Have a nice day.
