Description
11 SCK O
SPI Serial Clock output. Connect this pin to the SPI Serial Clock (SCK) signal of the
external device. Nominally reserved for SD/SDHC memory card or serial flash
memory chip.
See Section 8.3 for detailed timing diagram.
12 SDI I
SPI Serial Data Input. Connect this pin to the SPI Serial Data Out (SDO) signal of
the external device. Nominally reserved for SD/SDHC memory card or serial flash
memory chip.
See Section 8.3 for detailed timing diagram.
13 SDO O
SPI Serial Data Output. Connect this pin to the SPI Serial Data In (SDI) signal of the
external device. Nominally reserved for SD/SDHC memory card or serial flash
memory chip.
See Section 8.3 for detailed timing diagram.
14 TX0 O
Asynchronous Serial Transmit pin. Output data is at TTL voltage levels. Connect
this pin to external device Serial Receive (Rx) signal. This pin is tolerant up to 5.0V
levels.
15 RX0 I
Asynchronous Serial Receive pin. Connect this pin to external device Serial
Transmit (Tx) signal. This pin is tolerant up to 5.0V levels.
