After the device has completed POR and entered the Standby state, any later transition to the Hardware
Reset state will initiate the Warm Reset Embedded Algorithm. A Warm Reset is much shorter than a Cold
Reset, taking tens of µs (t
is stopped and the EAC is returned to its POR state without reloading EAC algorithms from non-volatile
memory. After the Warm Reset EA completes, the interface will remain in the Hardware Reset state if
RESET# remains Low. When RESET# returns High the interface will transit to the Standby state. If RESET#
is High at the end of the Warm Reset EA, the interface will directly transit to the Standby state.
If POR has not been properly completed by the end of t
cause a transition to the Power-on Reset interface state and initiate the Cold Reset Embedded Algorithm.
This ensures the device can complete a Cold Reset even if some aspect of the system Power-On voltage
ramp-up causes the POR to not initiate or complete correctly. The RY/BY# pin is Low during cold or warm
reset as an indication that the device is busy performing reset operations. Hardware (Warm) Reset
Hardware Reset is initiated by the RESET# signal going to V
