What are the right PINs for the two UARTs on the ADuC7128 and AduC7129 ?
This is not absolute clear or easy to understand in the datasheet.
The best place to understand this is in my opinion
table 76 on page 57 of the datasheet REV.0.
The ADuC7128 is in a 64-pin package and the ADuC7129 is in a 80-pin package.
There is a small fault in that table - P2.0 is available also on the 64-pin ADuC7128.
So not all signals (usually not used modem control lines for UART1) are not available
for the smaller package (64-pin) of the ADuC7128.
Here a quick help for the data lines :
UART 0 RX P1.0 or P0.7
UART 0 TX P1.1 or P2.0
UART1 RX P4.6
UART1 TX P4.7
P1.0 50 62
P1.1 49 61
P0.7 34 41
P2.0 33 40
P4.6 13 17
P4.7 14 18
