Read-only register. | Read-only register. Identifies the maximum mode-switching capabilities of the SoC. | ||
* CTR: O3DS | |||
* LGR1: N3DS prototype, 4 cores (orginally 2), up to 535MHz, no L2C (see below) | |||
* LGR2: retail N3DS, 4 cores, up to 804MHz, has L2C | |||
Kernel code suggests that devices that support LGR1 but not LGR2 only had 2 cores. All cores (the number of which can be read from MPCORE SCU registers) are usable in LGR1 mode. | |||
