Field : enable_shift_card | |
Control for the amount of phase shift provided on the default enables in the design. Two bits are assigned for each card/slot. For example, bits[1:0] control slot0 and indicate the following. ■ 00 Default phase shift ■ 01 Enables shifted to next immediate positive edge ■ 10 Enables shifted to next immediate negative edge ■ 11 Reserved Field Access Macros: | |

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
