Reading the Wake-Up Source Flag
When a wake-up event is detected in sleep mode, the
MAX13020/MAX13021 transition to standby mode and
present the wake-up source flag on TXD as a strong
pulldown in the case of a local wake-up. In the case of
a remote wake-up event, TXD is pulled to ground only
by an internal resistor. The wake-up source flag can be
determined by connecting a pullup resistor to TXD.
Choose the external pullup resistor such that TXD is a
logic-high when a remote wake-up occurs, and when a
local wake-up occurs and the strong pulldown drives
TXD low.
