Todo List

Global ISR (func, int_grp, int_lvl)

Update to use IRQ numbers when these are made available in the device header files of both IAR and GCC.

Global set_clock_divider (volatile avr32_ssc_t *ssc, unsigned int bit_rate, unsigned int pba_hz)

check input values

Global ssc_i2s_init (volatile avr32_ssc_t *ssc, unsigned int sample_frequency, unsigned int data_bit_res, unsigned int frame_bit_res, unsigned char mode, unsigned int pba_hz)

check input values

Global usb_device_task_init (void)

Implement this on the silicon version

Group USBB_host_driver

Implement macros for endpoint DMA registers and descriptors
