104 | \ PRTAD is a hardware implementation detail | |
105 | \ Various bcm8704 registers have different DEVAD. Registers | |
106 | \ with addresses 0xC800 and C803 belong to DEVAD=3, the other | |
107 | \ registers belong to DEVAD=4. | |
108 | \ | |
109 | \ So for the registers with address offset C80x, we have, | |

116 | \ P1 Rd C80x: 00 11 01001 00011 10 = 348E.XXXX | |
117 | \ | |
118 | \ And for the register with address offset 80x6, we have, | |
119 | \ ST OP PRTAD DEVAD TA | |
120 | \ P1 Addr 80x6: 00 00 01001 00100 10 = 0492.AAAA | |
