Function
CS_EX is decoded in the CS0 memory space and is
located in the address range 400000h–7FFFFFh.
CS_EX is decoded in the CS2 memory space and is
located in the address range A00000h–A7FFFFh.
CS_EX is decoded in the CS2 memory space and is
located in the address range A80000h–AFFFFFh.
CS_EX is decoded in the CS2 memory space and is
located in the address range B00000h–B7FFFFh.
Function
The Termination Resistor for RS485_2 is IN.
The Termination Resistor for RS485_2 is OUT.
Jumper J18
The J18 jumper connection controls the selection of the RS485 termina-
tion resistor circuit. When the shunt is placed, the RS485 termination
resistor circuit is enabled. See Table 21.
Jumper J19
The J19 jumper connection selects the range of memory addresses for the
external chip select signal, CS_EX, to the application module. See
Table 22.
