[FAQ] TDA4VM: How to check if R5F is in lock-step or split mode

The c15, Build Options 2 register can be used to check this.

To view this register we can use CP15 registers from System Registers.

Registers -> System_Registers -> CP15_BUILD_OPTIONS_2 register. The bit 30 (LOCK_STEP) here denotes if the R5F is in Lock-step or split mode. 

30th Bit:

0 :: Split mode

1 :: Lock step mode
