7.3.3
CR02 can only be accessed in the configuration state and after the CSR has been initialized to 02H. The default
value of this register after power up is 88H (Table 27).
Table 27 - CR02
BIT NO.
BIT NAME
0:2
Reserved
Read Only. A read returns “0”.
3
UART1 Power Down
1
A high level on this bit, allows normal operation of the Primary
Serial Port (Default). A low level on this bit places the Primary
Serial Port into Power Down Mode.
4:6
Reserved
Read Only. A read returns “0”.
7
UART2 Power Down
1
A high level on this bit, allows normal operation of the
Secondary Serial Port, including the SCE block (Default). A
low level on this bit places the Secondary Serial Port including
the SCE block into Power Down Mode.
Note
1
:
Power Down bits disable the respective logical device and associated pins, however the power down bit
does not disable the selected address range for the logical device. To disable the host address registers the
logical device’s base address must be set below 100h. Devices that are powered down but still reside at a
valid I/O base address will participate in Plug-and-Play range checking.
