u16 N PHY Gen Load Samples (u32 freq, u16 max, u8 test)

This routine uses a macro CONVERT(X) defined as (((X) >= 0) ? ((((X) >> 15) + 1) >> 1) : -((((-(X)) >> 15) + 1) >> 1))

1. If the band width is 40 MHz
   1. Set bw to 40
2. Otherwise
   1. Set bw to 20

3. Set len to bw << 3

4. If test is 1
   1. Read PHY Register 0x01, right shift by 15 and mask with 1
   2. If the result of the previous step is 1
      1. Set bw to 82
   3. Otherwise
      1. Set bw to 80
   4. If the band width is 40 MHz

      1. Set bw to bw << 1

   5. Set len to bw << 1

5. Allocate a complex u32 buffer of length len

6. Set rot to (((freq * 36) / bw) << 16) / 100

7. Set angle to 0
8. Loop len times with i as index

   1. Call PHY Cordic with angle and buffer[i] as arguments

   2. Increase angle by rot
   3. Set buffer[i].q to CONVERT(buffer[i].q * max)
   4. Set buffer[i].i to CONVERT(buffer[i].i * max)

9. Call N PHY Load Sample Table with buffer, len as arguments

10. Free buffer
11. Return len
