IP Reset Control Resister1
| CHIP_RST | CHIP one shot reset (write-protection bit) Setting this bit will reset the whole chip, including CPU kernel and all peripherals, and this bit will automatically return to 0 after the 2 clock cycles. The CHIP_RST is same as the POR reset, all the chip controllers is reset and the chip setting from flash are also reload. About the difference between CHIP_RST and SYSRESETREQ, please refer to section 5.2.2 of TRM. This bit is the protected bit. It means programming this bit needs to write “59h”, “16h”, “88h” to address 0x5000_0100 to disable register protection. Reference the register REGWRPROT at address GCR_BA+0x100. 1 = CHIP one shot reset 0 = CHIP normal operation |
| CPU_RST | CPU kernel one shot reset (write-protection bit) Setting this bit will only reset the CPU kernel and Flash Memory Controller(FMC), and this bit will automatically return to 0 after the 2 clock cycles This bit is the protected bit, It means programming this bit needs to write “59h”, “16h”, “88h” to address 0x5000_0100 to disable register protection. Reference the register REGWRPROT at address GCR_BA+0x100. 1 = CPU one shot reset 0 = CPU normal operation |
| PDMA_RST | PDMA Controller Reset (write-protection bit in NUC100/NUC120/NUC130/NUC140 Low Density and NUC101) Setting this bit to 1 will generate a reset signal to the PDMA. User need to set this bit to 0 to release from reset state This bit is the protected bit, It means programming this bit needs to write “59h”, “16h”, “88h” to address 0x5000_0100 to disable register protection. Reference the register REGWRPROT at address GCR_BA+0x100 1 = PDMA controller reset 0 = PDMA controller normal operation |
| EBI_RST | EBI Controller Reset (write-protection bit in NUC100/NUC120/NUC130/NUC140 Low Density 64-pin package) Set this bit to 1 will generate a reset signal to the EBI. User need to set this bit to 0 to release from the reset state. This bit is the protected bit, It means programming this bit needs to write “59h”, “16h”, “88h” to address 0x5000_0100 to disable register protection. Reference the register REGWRPROT at address GCR_BA+0x100. 1 = EBI controller reset 0 = EBI controller normal operation |
