11.2.9 UARTn1 Mode Register (UAn1MOD)
UAn1MOD is a specific function register (SFR) to set the transfer mode in UARTn1 half-duplex communication mode.
When the full-duplex communication is chosen, no need to specify this register.
Address: 0xF614(UA01MODL/UA01CON), 0xF615(UA01MODH),
0xF634(UA11MODL/UA11MOD), 0xF635(UA11MODH),
0xF654(UA21MODL/UA21CON), 0xF655(UA21MODH),
0xF674(UA31MODL/UA31MOD), 0xF675(UA31MODH),
0xF694(UA41MODL/UA41CON), 0xF695(UA41MODH),
0xF6B4(UA51MODL/UA51MOD), 0xF6B5(UA51MODH)
