DS3181/DS3182/DS3183/DS3184
Bit 5: Receive New Pattern Load (RNPL) – A zero to one transition of this bit will cause the programmed test
pattern (QRSS, PTS, PLF[4:0}, PTF[4:0], and BSP[31:0]) to be loaded in to the receive pattern generator. This bit
must be changed to zero and back to one for another pattern to be loaded. Loading a new pattern will forces the
receive pattern generator out of the “Sync” state which causes a re-synchronization to be initiated.
Note: QRSS, PTS, PLF[4:0}, PTF[4:0], and BSP[31:0] must not change from the time this bit transitions from 0 to 1
until four receive clock cycles after this bit transitions from 0 to 1. Register bit PORT.CR1.BENA must be set and
the receive clock running in order for the pattern load to take affect.
Bit 4: Receive Pattern Inversion Control (RPIC) – When 0, the receive incoming data stream is not altered.
When 1, the receive incoming data stream is inverted.
Bit 3: Manual Pattern Re-synchronization (MPR) – A zero to one transition of this bit will cause the receive
pattern generator to re-synchronize to the incoming pattern. This bit must be changed to zero and back to one for
another re-synchronization to be initiated. Note: A manual re-synchronization forces the receive pattern generator
out of the “Sync” state.
Bit 2: Automatic Pattern Resynchronization Disable (APRD) – When 0, the receive pattern generator will
automatically re-synchronize to the incoming pattern if six or more times during the current 64-bit window the
incoming data stream bit and the receive pattern generator output bit did not match. When 1, the receive pattern
generator will not automatically re-synchronize to the incoming pattern.
Bit 1: Transmit New Pattern Load (TNPL) – A zero to one transition of this bit will cause the programmed test
pattern (QRSS, PTS, PLF[4:0}, PTF[4:0], and BSP[31:0]) to be loaded in to the transmit pattern generator. This bit
must be changed to zero and back to one for another pattern to be loaded.
Note: QRSS, PTS, PLF[4:0}, PTF[4:0], and BSP[31:0] must not change from the time this bit transitions from 0 to 1
until four transmit clock cycles after this bit transitions from 0 to 1. Register bit PORT.CR1.BENA must be set and
the transmit clock running in order for the pattern load to take affect.
Bit 0: Transmit Pattern Inversion Control (TPIC) – When 0, the transmit outgoing data stream is not altered.
When 1, the transmit outgoing data stream is inverted.
