Function Documentation

bool ctr_detect_a9lh_entry

(

void

)

Returns whether the arm9 entry was a9lh or not.

Returns

True if the arm9 entrypoint was a9lh, false otherwise.

void ctr_flush_cache

(

void

)

Flushes all of the ARM9 CPU caches, and drains the write buffer.

Postcondition

All CPU caches (instruction and data) have been flushed, and the write buffer has been drained.

ctr_system_type ctr_get_system_type

(

void

)

Returns the enumeration corresponding to the running system.

Returns

The type of system this is called in.

void ctr_system_poweroff

(

void

)

Powers off the 3DS.

This function does not return. It powers off the 3DS via an i2c call to the MPU.

Postcondition

3DS has powered off.

void ctr_system_reset

(

void

)

Resets the 3DS.

This function does not return. It resets the 3DS via an i2c call to the MPU.

Postcondition

3DS has restarted.

void ctr_twl_keyslot_setup

(

void

)

Sets up the TWL keyslot.

This only really matters if arm9 execution is obtained via a9lh, or prior to a FIRM load. Nothing happens if FIRM had been launched previously.

Postcondition

The TWL keyslot is setup properly.
