The contents of each hardware register are shown. For each register, the preset value is displayed
for both ASYN (MAP27) and SYNC (HDLC) modes. The user should verify the current state of
the system (Async or Sync) before comparing the contents of the register to one of the preset
values.
1. CURRENT MODE of operation.(ASYNC_MODE=0 , SYNC_MODE=1)
