Driving strength and slew rate programmability

The IO Driving Strength is programmable for the following interfaces as follows:

●

SD/MMC0

(4, 6, 8 mA)

(default 8mA)

●

SD/MMC1

(4, 6, 8 mA)

(default 8mA)

●

SD/MMC2

(4, 6, 8 mA)

(default 8mA)

●

LCD

(4, 8 mA)

(default 8mA)

●

DRAM

(weak 70

Ω, strong 50Ω)

(default strong, 50

Ω)

●

FSMC

(4, 8 mA)

(default 8mA)

The Slew Rate is also controllable for the following interface as follows:

●

SD/MMC0

(Nominal, Fast)

(default Nominal slew rate)

●

SD/MMC1

(Nominal, Fast)

(default Nominal slew rate)

●

SD/MMC2

(Nominal, Fast)

(default Nominal slew rate)

●

LCD

(Nominal, Fast)

(default Fast slew rate)

●

FSMC

(Nominal, Fast)

●

DRAM

(200, 266, 333 MHz)

(default 200 MHz)

●

ULPI

(Nominal, Fast)

(default Fast slew rate)

●

MSP0

(Nominal, Fast)

(default Nominal slew rate)

●

MSP1

(Nominal, Fast)

(default Nominal slew rate)
