We would like to use UPP channel A in 16-bit mode, but we have limited pins available in our application. Our existing OMAP-L138 pin usage only gives us access to UPP channel A control signals plus UPP DATA[7:0] and XDATA[7:0]. According to the TRM, the XDATA pins are only available when using UPP dual channel mode (see table 33-3 below). Is it possible to use the highlighted configuration (CHN=1, IWA=1, IWB=0) to gain access to full 16-bit bus on channel A even though channel B is not used in the application? The pin multiplexing for channel B control signals would be configured for other, non-UPP functions.
