+-- Purpose:
+--  TX/RX frame counters clear command.
+--
+-- Verifies:
+--  1. TX Frame counter is cleared by COMMAND[TXRFCRST].
+--  2. TX Frame counter is not cleared by COMMAND[TXFRCRST].
+--  3. RX Frame counter is cleared by COMMAND[RXRFCRST].
+--  4. RX Frame counter is not cleared by COMMAND[RXFRCRST].
+--
+-- Test sequence:
+--  1. Generate and send frame by Node 2. Check that TX frame counter of Node 2
+--     is not zero. Issue COMMAND[RXFRCRST] and check it is still not 0. Issue
+--     COMMAND[TXFRCRST] and check it is 0 now.
+--  2. Check that RX Frame counter of Node 1 is not zero. Issue COMMAND[TXFRCRST]
+--     and check it is still not 0. Issue COMMAND[RXFRCRST] and RX Frame counter
+--     in Node 1 is 0.
