unsigned char smc_get_cs_size

(

unsigned char

cs

)

Return the size of the peripheral connected .

Parameters

cs	The chip select value

References smc_tab_cs_size.

void smc_init

(

unsigned long

hsb_hz

)

Initializes the AVR32 SMC module and the connected SRAM(s).

Parameters

hsb_hz

HSB frequency in Hz (the HSB frequency is applied to the SMC).

Note

Each access to the SMC address space validates the mode of the SMC and generates an operation corresponding to this mode.
