IN port parameters

[JohnR]

Hi,

The code below is generated by the compiler in creating an IN port, in this case named 'start'

Code: Select all

          ldw       r0, dp[start] 
          setc      res[r0], 0x8
          ldc       r1, 0x6
          setclk    res[r0], r1

Is there any documentation that defines the value 0x6 that is provided to the clock resource.

Thanks in advance,

John

0x6 is just the number of the clock block. This is discussed on page 25 of the XS1 Architecture document - see http://www.xmos.com/system/files/xs1_en.pdf

[ We have noted the error - "A clock c which is to use a port p as its clock source can be connected to it by executing a SETCLK c, p instruction." which should read
"A clock c which is to use a port p as its clock source can be connected to it by executing a SETCLK p, c instruction." ]
