3.5 Serial GATEWAY mode

This mode can be used, if the time the target is freezed in BDM Gateway mode is not acceptable (e.g.
interrupt response time). In order to use this mode, there must be a free serial channel on the target
(e.g. a SCC channel). The processors or UART’s RX/TX pins can be directly used because the
BDI2000 needs and drives Vdd I/O levels (Rev. A/B TTL levels). There is no need for a RS232 level
converter.

3.5.1 Target connection

The two communication lines (RX/TX) and optional an additional GROUND has to be connected be-
tween the BDI2000 and the target. The cable length should not exceed 50 cm (20").

Be sure to connect GTW-TX to the target RX pin and GTW-RX to the target TX pin.

Maximal input voltage to BDI2000 must not exceed 5.5V
