SCI/LIN interface (J16, J17, P21, P25, P26)
The Vybrid SCI0 channel is shared on the EVB by the two serial interfaces - SCI and LIN, selection being
provided by jumpers J16 and J17 (see
Table 15
).
11.2.1
SCI configuration (P26)
To provide signal translation, the EVB SCI interface has a RS232 transceiver (U10), which is:
•
Connected to a standard 9-way female D-type connector (P26) allowing a direct connection to a
PC or terminal, pinout being shown in
,
•
Providing no hardware flow control support.
