Function
X1
I
Input of the on-chip inverting oscillator amplifier
To use the internal oscillator, a crystal/resonator circuit is connected to
this pin. If an external oscillator is used, its output is connected to this
pin. X1 is the clock source for internal timing.
-
X2
O
Output of the on-chip inverting oscillator amplifier
To use the internal oscillator, a crystal/resonator circuit is connected to
this pin. If an external oscillator is used, leave X2 unconnected.

SDCMD
I/O
SD/MMC Command Line
Bidirectional command line used for commands and responses transfer.
P2.2
SDDAT3:0
I/O
SD/MMC Data Lines
Bidirectional data lines. In 1-bit mode configuration SDDAT0 is the DAT
signal and SDDAT3:1 are not used and can be reused as I/O ports.
P2.7:4
SDINS
I
SD/MMC Card Insertion Signal
SDINS is the card presence signal. A low level on this input indicates
the card is present in its slot.
Note:
This signal is generated by the SD/MMC card connector.
P2.0
SDLCK
I
SD Card Write Lock Signal
SDLCK is the SD Card write protected input. A low level on this pin
indicates the card is write protected.
Note:
This signal is generated by the SD/MMC card connector.
