CSORBT and CSOR[0:10] contain parameters that support operations from external
memory devices. Bit and field definitions for CSORBT and CSOR[0:10] are the same.
In asynchronous mode, chip-select assertion is synchronized with AS and DS.
In synchronous mode, the chip-select signal is asserted with ECLK.
This field is used only when the chip-select 16-bit port option is selected in the pin
assignment register. This allows the usage of two external 8-bit memory devices to be
concatenated to form a 16-bit memory. Table D-13 shows upper/lower byte options.
This field causes a chip-select to be asserted only for a read, only for a write, or for
both reads and writes. Table D-14 shows the options.
0 = Asynchronous mode is selected.
1 = Synchronous mode is selected, and used with ECLK peripherals.
