Lattice Semiconductor
The SERDES characterization test mode is configured by setting bits in the control registers via the system bus.
The transmit characterization test mode is entered when SCHAR_ENA= “1” (address 30830, bit 4) and
SCHAR_TXSEL= “1” (address 30830, bit 5). Entering this mode will cause chip port inputs to directly control the
SERDES low-speed transmit ports of one of the channels as shown in Table 39.
Table 39. SERDES Transmit Characterization Mode
The x in the table represents a single channel in the SERDES QUAD, selected by the SCHAR_CHAN control bits
(address 30830, bits 6 and 7). The decoding of SCHAR_CHAN is shown in Table 40.
Table 40. Decoding of SCHAR_CHAN
The receive characterization test mode is entered as long as TESTMD[1:0]N = 00. In this mode, one of the chan-
nels of SERDES outputs is observed at chip ports as shown in Table 41. The channel that is observed is also
based on the decoding of SCHAR_CHAN as shown in Table 40. The receive characterization pins can be observed
independently, whether the transmit characterization pins are enabled or not.
