The ARM11 loads this value from 0x1FFFFFF0+1 during startup, which is written by the ARM9 during ARM9<>ARM11 kernel sync. | |||
When this field is zero, bit0 for UNITINFO is set for retail. When this field is non-zero, bit0 for UNITINFO is clear for dev/debug units, and an ARM11 kernel state flag which enables debugging is set. Bit1 means JTAG connected. | When this field is zero, bit0 for UNITINFO is set for retail.

This originates from the low 8-bits of register [[CONFIG|0x10010000]]. When bit0 is set, the ARM11 kernel will not set the UPDATEFLAG to value 1. | This originates from the low 8-bits of register [[CONFIG|0x10010000]]. When bit0 is set, the ARM11 kernel will not set the UPDATEFLAG to value 1. | ||
