CR24
This register can only be accessed in the Configuration
Mode and after the CSR has been initialized to 25H.
The default value of this register after power up is 00H.
This register is used to select the base address of UART1
(serial port 1).
CR25
This register can only be accessed in the Configuration
Mode and after the CSR has been initialized to 25H. The
default value of this register after power up is 00H. This
register is used to select the base address of UART2
(serial port 2).
