sync the GCLK0 output and RK output of SSC to F_CPU/32
BTW, I just notice the following interesting code: static void pm_set_osc0_mode(volatile avr32_pm_t *pm, unsigned int mode) { // Read u_avr32_pm_oscctrl0_t...

sync the GCLK0 output and RK output of SSC to F_CPU/32
Hi, Ben thanks for the reply. I use a 16MHz crystal on OSC0 and yes, FOSC0 is 16MHz and OSC0_STARTUP is fine with the crystal. I still don't understand why my code would have...

yes, right, I will repolish this to AVR32 forum.

does BITS field setting in CSR0-3 take effect immediately?
and I found out that you have to read out RDR value before you change the bits setting, otherwise the RDR reading would be different.

does BITS field setting in CSR0-3 take effect immediately?
i just did some more test, and it seems this LASTXFER will indeed rise the CSn pin after the transfer finish. If I don't add this LASTXFER in the last transfer, then the CSn pin...

I don't understand the Figure 21-6. Master Mode Flow Diagram S in the datasheet. it didn't mention the LASTXFER bit setting. if I have set the LASTXFER bit in the last transfer,...

does BITS field setting in CSR0-3 take effect immediately?
no, I'm not using DMA. Yes, I have read the errata for SPI. But there have no information about the CSAAT. And surprisingly, after I updated the framework to 1.2 and avr32studio...

does BITS field setting in CSR0-3 take effect immediately?
I have tested the CSAAT bit, and it just doesn't work. I can't let the CSn pin to keep low between two data transfer. I have set the CSAAT bit before I start the two transfer, but...

just finished my _delay_loop_x code for AVR32, I did some simple test, it seems it's working. can you guys check it?

Inlined Delay Algorithm
I just can't find a single suitable instruction in AVR32 to use as _NOP2 or _NOP3 for the AVR32_delay_x, hehe, this means most of the AVR32 instructions are very fast, which is a...
