AC timing specs assume 40pF load capacitance on BCLK and a 50pF load capacitance on output pins. If this value is different,
the input and output timing specifications would need to be adjusted to match the clock load.
Outputs (8mA): DATA[31:16], ADDR[25,23:9]
Outputs (4mA): SDRAS, SDCAS, SDWE, SD_CS0, SDUDQM, SDLDQM, BCLKE
High Impedance (Three-State): DATA[31:16]

AC timing specs assume 50pF load capacitance on PSTCLK and output pins. If this value is different, the input and
output timing specifications would need to be adjusted to match the clock load.
DSCLK and DSI are internally synchronized. This setup time must be met only if recognition on a particular clock is
required.
