PRODUCTION DATA.
BIT | BIT NAME | DEFAULT | DESCRIPTION |
---|---|---|---|
15:8 | BIST_ERROR_CO UNT | 0, RO | BIST ERROR Counter: |
Counts number of errored data nibbles during Packet BIST. This value will reset when Packet BIST is restarted. The counter sticks when it reaches its max count. | |||
7:6 | RESERVED | 0, RW | RESERVED: Must be zero |
5 | BIST_CONT_MOD E | 0, RW | Packet BIST Continuous Mode: |
Allows continuous pseudo random data transmission without any break in transmission. This can be used for transmit VOD testing. This is used in conjunction with the BIST controls in the PHYCR Register (0x19h). For 10Mb operation, jabber function must be disabled, bit 0 of the 10BTSCR (0x1Ah), JABBER_DIS = 1. | |||
4 | CDPATTEN_10 | 0, RW | CD Pattern Enable for 10Mb: |
1 = Enabled | |||
0 = Disabled | |||
3 | RESERVED | 0, RW | RESERVED: Must be zero |
2 | 10MEG_PATT_GA P | 0, RW | Defines gap between data or NLP test sequences: |
1 = 15 µs | |||
0 = 10 µs | |||
1:0 | CDPATTSEL[1:0] | 00, RW | CD Pattern Select[1:0]: |
If CDPATTEN_10 = 1: | |||
00 = Data, EOP0 sequence | |||
01 = Data, EOP1 sequence | |||
10 = NLPs | |||
11 = Constant Manchester 1s (10MHz sine wave) for harmonic distortion testing |
