Sets (1) or clears (0) the reset long PN sequence bit(PN23).
dev | - The device structure. |
rst | - Enable option. Example: 1 - The PN sequence is held in reset; 0 - The PN sequence resumes from the seed value(0x3AFF). |
int32_t ad9250_reset_PN29 | ( | struct ad9250_dev * | dev, |
int32_t | rst | ||
