BANK: SdramPinSet,
New SDRAM instance
_pins
must be a set of pins connecting to an SDRAM on the FMC
controller
Panics
-
Panics if there are not enough address lines in
PINS
to access the whole SDRAM -
Panics if there are not enough bank address lines in
PINS
to access the whole SDRAM
New SDRAM instance
bank
denotes which SDRAM bank to target. This can be either bank 1 or
bank 2.
Safety
The pins are not checked against the requirements for the SDRAM chip. So you may be able to initialise a SDRAM without enough pins to access the whole memory
Initialise SDRAM instance. Delay is used to wait the SDRAM powerup delay
Returns a raw pointer to the memory-mapped SDRAM block
Panics
-
Panics if any setting in
IC::CONFIG
cannot be achieved -
Panics if the FMC source clock is too fast for maximum SD clock in
IC::TIMING
