Manufacturer:MB Description:POWER-ON INITIALIZATION When power is first applied, power-on reset circuitry initial- izes the COMBO II and puts it into the power-down state. The gain control registers for the transmit and receive gain sections are programmed to OFF (00000000), the hybrid balance circuit is turned off, the power amp is disabled and the device is in the non-delayed timing mode. The Latch Di- rection Register (LDR) is pre-set with all IL pins programmed as inputs, placing the SLIC interface pins in a high imped- ance state. The CI/O pin is set as an input ready for the first control byte of the initialization sequence. Other initial states in the Control Register are indicated in Section 2.0. A reset to these same initial conditions may also be forced by driving the MR pin momentarily high. This may be done ei- ther when powered-up or down. For normal operation this pin must be pulled low. If not used, MR should be hard-wired to ground. The desired modes for all programmable functions may be initialized via the control port prior to a Power-up command. |
