20.3.1. Register Memory Map

Each address offset in the table below represents 1 word of memory address space.

Table 244.  Register Memory Map
Register Offset Width Access Description
FLASH_RD_STATUS 0x0 8 R Perform read operation on flash device status register and store the read back data.
FLASH_RD_RDID 0x2 32 R
  • Perform read operation to extract 20 bytes of flash device ID information.
  • Store the flash device ID into DEVICE_ID_DATA_* registers.
  • Store a copy of DEVICE_ID_DATA_0 in this register.
FLASH_MEM_OP 0x3 24 W To protect, erase, and write enable memory.

To perform write enable operation, set this register with the value 3'b100.

FLASH_CHIP_SELECT 0x6 3 W Chip select values:
  • B’000/b’001 -chip 1
  • B'010 - chip 2
  • B'100 - chip 3
EPCQ_FLAG_STATUS 0x7 8 RW Perform write/read operation to clear/read flag status from the device.
DEVICE_ID_DATA_0 0x8 32 R First word of device ID data
DEVICE_ID_DATA_1 0x9 32 R Second word of device ID data
DEVICE_ID_DATA_2 0xA 32 R Third word of device ID data
DEVICE_ID_DATA_3 0xB 32 R Fourth word of device ID data
DEVICE_ID_DATA_4 0xC 32 R Fifth word of device ID data
