The following configurations are possible:
Signal Configuration J200 J202
TxD1 and RxD1 with RS-232 levels 1 + 2* 1 + 2*
P08 and P09 as I/O pin or TxD1 and
RxD1 as interface signals with TTL level
2 + 3 2 + 3
* = Default setting
Table 3: J200, J202 Second Serial Interface Configuration
3.2 J201, J203 First Serial Interface
Jumper J201 and J203 connect the signals of the first synchronous/
asynchronous serial interface to the on-board RS-232 transceiver. The
interface signals are then available with RS-232 level at the
phyCORE-connector pins X700D22 (RxD0) and X700D23 (TxD0). If
the jumpers are opened, the applicable controller pins P00 and P01 can
be used with their alternative functions or the serial interface signals
are available with their TTL level at phyCORE-connector pins
X700D17 and X700D16.
If the jumpers are closed we recommend not to use the interface
signals with their TTL level as this will cause damage to the on-board
components.
The following configurations are possible:
Signal Configuration J201 J203
TxD0 and RxD0 with RS-232 level at
X700D22 and X700D23
1 + 2* 1 + 2*
TxD0 and RxD0 with TTL level or as
I/O pin at X700D22 and X700D23
2 + 3 2 + 3
P00 and P01 as I/O pin or TxD0 and
RxD0 interface signals with TTL level at
X700D16 and X700D17
