Pullup
Active-low. A back-end error sequence is generated by applying logic
LOW to this terminal. This terminal is connected to an external power
stage. If no external power stage is used, connect this terminal directly
to DVDD.
(1) TYPE: A = analog; D = 3.3-V digital; P = power/ground/decoupling; I = input; O = output
(2) All pullups are 20-µA weak pullups and all pulldowns are 20-µA weak pulldowns. The pullups and pulldowns are included to assure
proper input logic levels if the terminals are left unconnected (pullups logic 1 input; pulldowns logic 0 input). Devices that drive
inputs with pullups must be able to sink 20 µA while maintaining a logic-0 drive level. Devices that drive inputs with pulldowns must be
able to source 20 µA while maintaining a logic-1 drive level.
