The 2 KB I
kHz and the address is 0xA0.
The peripheral is connected directly to the EFM when the I2C bit in the PERCTRL register in the board
controller has been set.
The I
is -55 °C to +125 °C. The maximum bus speed is 400 kHz and the address is 0x90.
The peripheral is connected directly to the EFM when the I2C bit in the PERCTRL register in the board
controller has been set.
A 16 MBit SPI flash is connected to the SPI module of the EFM.
The peripheral is connected directly to the EFM when the SPI bit in the PERCTRL register in the board
controller has been set. To route the chip select correctly, the FLASH bit in the BC_SPI_CFG register
in the board controller must also be set.
A microSD slot is connected to the SPI module of the EFM.
The peripheral is connected directly to the EFM when the SPI bit in the PERCTRL register in the board
controller has been set. To route the chip select correctly, the MICROSD bit in the BC_SPI_CFG register
in the board controller must also be set.
The TFT LCD can be accessed from the EFM through the board controller. The interface can be
configured to be either 9 bit or 16 bit. This selection is done by setting the 16BIT bit in the DISPLAY_CTRL
register in the board controller. It is also possible to use the SPI interface, but then the R112 resistor
must be moved over to the position of R112.
Note
The 512 KB SRAM can be accessed from the EFM through the board controller. The data width is either
8 or 16 bit, depending on the access method.
The 4 MB NOR Flash can be accessed from the EFM through the board controller. The data width is
either 8 or 16 bit, depending on the access method.
