Table 5-1 Power-On Reset (POR) and Brown-Out Reset (BOR) Term Definitions

TERM DEFINITION
VGH V33D threshold where the internal power is declared good. The device exits the reset state when above this threshold.
VGL V33D threshold where the internal power is declared bad. The device enters reset state when below this threshold.
Vres V33D threshold where the internal reset signal is no longer valid. Below this threshold the device is in an indeterminate state.
IReset The internal reset signal. When low, the device is held in reset. This is equivalent to holding the device reset pin high.
tPOR The time delay from when the VGH threshold exceeded to when the device exits the reset state.
Brown-out The V33D voltage threshold at which the device sets the brown out status bit. An interrupt can be triggered if enabled.
