PRODUCTION DATA
Register Name | Address | Bit | Name | Function | Default Value |
---|---|---|---|---|---|
config1 | 0x01 | 15 | iotest_ena | When set, enables the data pattern checker test. The outputs are deactivated regardless of the state of TXENABLE and sif_txenable. | 0 |
14 | Reserved | Reserved for factory use. | 0 | ||
13 | Reserved | Reserved for factory use. | 0 | ||
12 | 64cnt_ena | When set, enables resetting of the alarms after 64 good samples with the goal of removing unnecessary errors. For instance, when checking setup/hold through the pattern checker test, there may initially be errors. Setting this bit removes the need for a SIF write to clear the alarm register. | 0 | ||
11 | oddeven_parity | Selects between odd and even parity check 0: Even parity 1: Odd parity | 0 | ||
10 | word_parity_ena | When set, enables parity checking of each input word using the PARITYP/N parity input. It should match the oddeven_parity register setting. | 1 | ||
9 | frame_parity_ena | When set, enables parity checking using the FRAME signal to source the parity bit. | 0 | ||
8 | Reserved | Reserved for factory use. Note: Default value is 1b. Must be set to 0b for proper operation | 1 | ||
7 | Reserved | Reserved for factory use. | 0 | ||
6 | dacI_complement | When set, the DACI output is complemented. This allows to effectively change the + and – designations of the LVDS data lines. | 0 | ||
5 | dacQ_complement | When set, the DACQ output is complemented. This allows to effectively change the + and – designations of the LVDS data lines. | 0 | ||
4 | Reserved | Reserved for factory use. | 0 | ||
3 | alarm_2away_ena | When set, the alarm from the FIFO indicating the write and read pointers being 2 away is enabled. | 1 | ||
2 | alarm_1away_ena | When set, the alarm from the FIFO indicating the write and read pointers being 1 away is enabled. | 1 | ||
1 | alarm_collision_ena | When set, the alarm from the FIFO indicating a collision between the write and read pointers is enabled. | 1 | ||
0 | Reserved | Reserved for factory use. | 0 |
