-- Purpose:
-- ERR_CAPT[ERR_POS] = ERC_POS_SOF feature test.
--
-- Verifies:
-- 1. Detection of form error in SOF bit.
--
-- Test sequence:
-- 1. Generate CAN frame and send it by Node 1. Wait until transmission starts
-- and force bus Recessive. Wait until sample point and check that Error
-- frame is transmitted. Check that ERR_CAPT says that Form Error during
-- SOF was detected!
