This register contains the control parameters for each SDRAM memory bank

Structs§

  • Register SDCR reader
  • This register contains the control parameters for each SDRAM memory bank
  • Register SDCR writer

Type Aliases§

  • Field CAS reader - CAS Latency This bits sets the SDRAM CAS latency in number of memory clock cycles
  • Field CAS writer - CAS Latency This bits sets the SDRAM CAS latency in number of memory clock cycles
  • Field MWID reader - Memory data bus width. These bits define the memory device width.
  • Field MWID writer - Memory data bus width. These bits define the memory device width.
  • Field NB reader - Number of internal banks This bit sets the number of internal banks.
  • Field NB writer - Number of internal banks This bit sets the number of internal banks.
  • Field NC reader - Number of column address bits These bits define the number of bits of a column address.
  • Field NC writer - Number of column address bits These bits define the number of bits of a column address.
  • Field NR reader - Number of row address bits These bits define the number of bits of a row address.
  • Field NR writer - Number of row address bits These bits define the number of bits of a row address.
  • Field RBURST reader - Burst read This bit enables burst read mode. The SDRAM controller anticipates the next read commands during the CAS latency and stores data in the Read FIFO. Note: The corresponding bit in the FMC_SDCR2 register is read only.
  • Field RBURST writer - Burst read This bit enables burst read mode. The SDRAM controller anticipates the next read commands during the CAS latency and stores data in the Read FIFO. Note: The corresponding bit in the FMC_SDCR2 register is read only.
  • Field RPIPE reader - Read pipe These bits define the delay, in KCK_FMC clock cycles, for reading data after CAS latency. Note: The corresponding bits in the FMC_SDCR2 register is read only.
  • Field RPIPE writer - Read pipe These bits define the delay, in KCK_FMC clock cycles, for reading data after CAS latency. Note: The corresponding bits in the FMC_SDCR2 register is read only.
  • Field SDCLK reader - SDRAM clock configuration These bits define the SDRAM clock period for both SDRAM banks and allow disabling the clock before changing the frequency. In this case the SDRAM must be re-initialized. Note: The corresponding bits in the FMC_SDCR2 register is read only.
  • Field SDCLK writer - SDRAM clock configuration These bits define the SDRAM clock period for both SDRAM banks and allow disabling the clock before changing the frequency. In this case the SDRAM must be re-initialized. Note: The corresponding bits in the FMC_SDCR2 register is read only.
  • Field WP reader - Write protection This bit enables write mode access to the SDRAM bank.
  • Field WP writer - Write protection This bit enables write mode access to the SDRAM bank.
