27 / 156 page ALC5642-VF Datasheet Multi-Channel Audio Hub/CODEC with embedded Voice DSP and SounzReal TM Digital Sound Effect 15 Rev. 0.93 7.3. Reset There are 2 types of reset operation: power on reset (POR) and register reset. Table 7. Reset Operation Reset Type Trigger Condition CODEC Response POR Monitor digital power supply voltage reach VPOR Reset all hardware logic and all registers to default values. Register Reset Write MX-00h Reset all registers to default values except some specify control registers and logic. 7.3.1. Power-On Reset (POR) When powered on, DCVDD passes through the VPOR band of the ALC5642 (VPOR_ON ~VPOR_OFF). A power on res et (POR) will generate an internal reset signal (POR reset ‘LOW’) to reset the whole chip. Table 8. Power-On Reset Voltage Symbol Min Typical Max Unit VPOR_ON - 0.8 - V VPOR_OFF - 0.52 - V Note: 1.VPOR_OFF must be below VPOR_ON 2. T oC = 25oC 3. When DCVDD is supplied 1.2V 7.3.2. Software Reset When MX-00h is wrote, all registers become to default value. |
