22.3.27 Transceiver Test Register 1 (TRNTREG1)
TRNTREG1 is a test register that can monitor the built-in transceiver input signal.
Setting bits PTSTE and txenl in TRNTREG0 to 1 enables monitoring the built-in transceiver input
signal. Table 22.5 shows the relationship between pin input and TRNTREG1 monitoring value.

Built-In Transceiver Input Signal Monitor
xver_data: Monitors the differential input level
(xver_data) signal of the built-in transceiver.
dpls: Monitors the USD+ (dpls) signal of the built-
in transceiver.
dmns: Monitors the USD- (dmns) signal of the built-
in transceiver.
Note:
