reset sequence
The DIR1703 requires external reset operation after power on. Figure 10 shows the reset sequence after power
on. The DIR1703 is ready for receiving S/PDIF signal when the internal reset sequence has finished and
CKTRNS goes to LOW. BFRAME, EMFLG, URBIT and CSBIT pins are used for configuration during the period
from the rising edge of RST to the falling edge of CKTRNS. S/PDIF signal is accepted after CKTRNS goes to
LOW. The minimum pulse width of RST, t
RST
is 100 ns. The RST delay after the power supply reaches 3 V should
be at least 10 ms. All of the output pins except CKTRNS and UNLOCK are LOW during RST LOW.

NOTE: SCF0 and SCF1 should be settled during RST assertion. The change of SCF0 and SCF1 is not permitted during normal operation. When
the change is needed, the reset sequence must be started by asserting RST again.
