DESCRIPTION
RESERVED FOR SMSC USE
7.3.19 CR12 - CR13
CR12 - CR13 are reserved and Read Only. The default value of these registers after power up is 00H.
7.3.20 CR14
(Reserved).
7.3.21 CR15
CR15 can only be accessed in the configuration state and after the CSR has been initialized to 15H. CR15 shadows
the bits in the write-only UART1 run-time FCR register (Table 39).
