ADVANCE PRODUCT INFORMATION JUL 26, 2011
6.4.3
The device latches the information of the wake-up source to distinguish beween a remote wake-up
request via LIN bus and local wake-up via pin WAKE_N. The wake-up source can be read on pin TXD
in the mode Standby and Power-on.
A HIGH level at pin TXD indicates a remote wake-up request (weak pull-up at pin TXD) and a LOW
level indicates a local wake-up request (strong pull-down at pin TXD).
6.4.4
The wake-up request flag and the wake-up source flag are reset after entering active mode. The wake-
up source signal at TXD and RXD is interrupted while pin EN is set to high in order to check flash mode
request at TXD.
