Field : Port User Priorities - userpriority | |
Set absolute user priority of the port. Each port is represented by a 3 bit value, 000=lowest priority, 111=highest priority. Port 0 is bits 2:0. Port number offset corresponds to the control port assignment. 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.
