POWER-UP SEQUENCE
On power-up, after the supplies are stable, the DS2154 should be configured for operation by writing to
all of the internal registers (this includes the Test Registers) since the contents of the internal registers
cannot be predicted on power-up. Next, the LIRST (CCR5.7) bit should be toggled from 0 to 1 to reset
the line interface circuitry (it will take the DS2154 about 40 ms to recover from the LIRST bit being
toggled). Finally, after the RSYSCLK and TSYSCLK inputs are stable, the ESR bit should be toggled
from a 0 to a 1 and then back to 0 (this step can be skipped if the elastic stores are not being used). Both
TCLK and RCLKI must be present for the parallel control port to operate properly.
