| This is a documentation subpage for Template:Reg8 (see that page for the template itself). It contains usage information, categories and other content that is not part of the original template page |
Usage
Use Template:reg8 for 8-bit registers. Make sure that the bit sizes add up and that your field count is correct. Fields with no name show up in dark grey.
{{reg8 | MAGIC_REGISTER | addr = 0x1337 | fields = 4
|7 !6 !5 !4 !3 !2 !1 !0 ! Bit
|3 |1 |1 |3 | Size
|U |R |R |W | Access
| |FOO |BAR |QUUX | Name
}}
Gives:
| MAGIC_REGISTER (0x1337) | ||||||||
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | |
| Access | U | R | R | W | ||||
| Field | FOO | BAR | QUUX | |||||
You can also omit some informational parts and collapse the layout; the result is the same:
{{User:Marcan/BitTest | MAGIC_REGISTER | addr = 0x1337 | fields = 4 |
|3 |1 |1 |3 |
|U |R |R |W |
| |FOO |BAR |QUUX |
}}
Gives:
| MAGIC_REGISTER (0x1337) | ||||||||
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | |
| Access | U | R | R | W | ||||
| Field | FOO | BAR | QUUX | |||||
Use Template:reg16 for 16-bit registers:
{{reg16 | MAGIC_REGISTER | addr = 0x1337 | fields = 5 |
|3 |1 |1 |5 |6 |
|U |R |R |W |W |
| |FOO |BAR |QUUX |LEETNESS |
|}}
Gives:
| MAGIC_REGISTER (0x1337) | ||||||||||||||||
| 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | |
| Access | U | R | R | W | W | |||||||||||
| Field | FOO | BAR | QUUX | LEETNESS | ||||||||||||
For 32-bit registers, the layout (and the template parameters) are split into two 16-bit halves:
{{reg32 | MAGIC_REGISTER | addr = 0x1337 | hifields = 5 | lofields = 6
|31 !30 !29 !28 !27 !26 !25 !24 !23 !22 !21 !20 !19 !18 !17 !16 ! Bit
|3 |1 |1 |5 |6 | Size
|U |R |R |W |W | Access
| |FOO |BAR |QUUX |LEETNESS | Name
|15 !14 !13 !12 !11 !10 !9 !8 !7 !6 !5 !4 !3 !2 !1 !0 ! Bit
|1 |2 |2 |8 |2 |1 | Size
|D |EA |DB |EE |F |? | Access
|! |FOO2 |BAR2 | |QUUX |EVIL| Name
}}
Or:
{{reg32 | MAGIC_REGISTER | addr = 0x1337 | hifields = 5 | lofields = 6 |
|3 |1 |1 |5 |6 |
|U |R |R |W |W |
| |FOO |BAR |QUUX |LEETNESS ||
|1 |2 |2 |8 |2 | 1 |
|D |EA |DB |EE |F | ? |
|! |FOO2 |BAR2 | |QUUX | EVIL |
}}
Both give:
| MAGIC_REGISTER (0x1337) | ||||||||||||||||
| 31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | |
| Access | U | R | R | W | W | |||||||||||
| Field | FOO | BAR | QUUX | LEETNESS | ||||||||||||
| 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | |
| Access | D | EA | DB | EE | F | ? | ||||||||||
