Hello,
Now I am developping the STM module of S32R274.
I want to make sure that which clock is used for STM counter calculation? System clock or PBRIDGE_n_CLK?
Backgrount: In the document "S32R274RM.pdf" :
1. page 155, figure 5-4 , we can see, the souce clock of STM is PBRIDGE_n_CLK
2. But in page 2356, we can see, the source clock is System clock : "The counter is driven by the system clock divided by an 8-bit prescale value (1
to 256)."
Thanks!
Solved! Go to Solution.
Hi, PBRIDGE_n_CLK is correct.
From module’s perspective it is system clock, unfortunately it is relic from internal documentation for the module. Figure 5-4 shows clock routing given by device integration and you may see both used clocks for STM are tied to PBRIDGE_n_CLK.
Hi David,
Thanks very much!
