General Purpose I/O Module
12.3.1.8 Drive Strength Control Registers (DSCR_x)
The drive strength control registers set the output pin drive strengths. All drive strength control
registers are read/write.
12.3.1.8.1 External Bus Drive Strength Control Register (DSCR_EIM)
The DSCR_EIM register controls the output drive strengths of several external bus pins: A[23:0],
D[31:0], BS[3:0], OE, R/W, CS[7:0], SD_SCAS, SD_SRAS, SD_WE, SCKE, SD_CS[1:0],
RSTOUT, TA, TEA, TIP, TS, and TSIZ[1:0].
