4.5 Power-Up Sequence
On power-up, after the supplies are stable, the DS2152 should be configured for operation by writing to
all the internal registers (this includes setting the Test Registers to 00 hex) since the contents of the
internal registers cannot be predicted on power-up. Finally, after the TSYSCLK and RSYSCLK inputs
are stable, the ESR bit should be toggled from 0 to 1 (this step can be skipped if the elastic stores are
disabled).
4.6 Remote Loopback
When CCR7.6 is set to 1, the DS2152 is forced into Remote Loopback (RLB). In this loopback, data
input via the RPOSI and RNEGI pins is transmitted back to the TPOSO and TNEGO pins. Data continues
to pass through the receive side framer of the DS2152 as it would normally, and the data from the
transmit side formatter is ignored. See Figure 1-1 for more details.
