| 16 | <ul> | |
| 17 | write-reg - write value to a register | |
| 18 | </ul> | |

| 20 | <h4>SYNOPSIS</h4> | |
| 21 | <tt> | |
| 22 | <ul> | |
| 23 | write-reg [-cpu <i>cpu_set</i>] | |
| 24 | [-cwp <i>window-pointer</i>] [-gl <i>global-level</i>] [-tl <i>trap-level</i>] | |
| 25 | <i>reg-name</i> <i>value</i> | |
| 26 | </ul> | |

| 29 | <h4>DESCRIPTION</h4> | |
| 30 | <ul> | |
| 31 | Set a cpu register. If <a href="flag_cpu.html">-cpu</a> is omitted, | |
| 32 | the current strand is used. | |
| 33 | Use <a href="cmd_cpuregs.html">cpuregs</a> command to show the supported register names. | |
| 34 | <p> | |
| 35 | By default, the current cwp register, global level, and trap level are | |
| 36 | used to access windowed registers, global registers, and trap | |
| 37 | registers, respectively. | |
| 38 | The -cwp, -gl, and -tl flags may be used to override these defaults. | |
