These functions are always called consecutively and are best bundled together for simplicity, especially when the same structure of callbacks will be replicated later on the interface block for INTF TE support. The enable_tearcheck(false) case is now replaced with a more obvious disable_tearcheck(), encapsulating the original register write with 0.
