MODES2=B_0x0, BUSY=B_0x0, RE=B_0x0, MODES1=B_0x0
SDRAM status register
| RE | Refresh error flag An interrupt is generated if REIE = 1 and RE = 1 0 (B_0x0): No refresh error has been detected 1 (B_0x1): A refresh error has been detected |
| MODES1 | Status Mode for Bank 1 This bit defines the Status Mode of SDRAM Bank 1. 0 (B_0x0): Normal Mode 1 (B_0x1): Self-refresh mode 2 (B_0x2): Power-down mode |
| MODES2 | Status Mode for Bank 2 This bit defines the Status Mode of SDRAM Bank 2. 0 (B_0x0): Normal Mode 1 (B_0x1): Self-refresh mode 2 (B_0x2): Power-down mode |
| BUSY | Busy status This bit defines the status of the SDRAM controller after a Command Mode request 1; SDRAM Controller is not ready to accept a new request 0 (B_0x0): SDRAM Controller is ready to accept a new request |
