EBI Controller Reset (write-protection bit in NUC130/NUC140 100-pin and 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
PDMA Controller Reset (write-protection bit in NUC130/NUC140)
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
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
