CR10 can only be accessed in the configuration state and after the CSR has been initialized to 10H.
CR10 is a test control register and all bits must be treated as Reserved. NOTE: All test modes are
reserved for SMSC use. Activating test mode registers may produce undesired results.
CR11
CR11 can only be accessed in the configuration state and after the CSR has been initialized to 11H.
CR11 is a test control register and all bits must be treated as Reserved. NOTE: all test modes are
reserved for SMSC use. Activating test mode registers may produce undesired results.
CR12 - CR13
CR12 and CR13 are the LPC47N227 Configuration Ports base address registers (Table 73 and Table
74). These registers are used to relocate the Configuration Ports base address beyond the power-up
defaults determined by the SYSOPT pin programming.
CR12 contains the Configuration Ports base address bits A[7:0]. CR13 contains the Configuration
Ports base address bits A[10:8]. The address bits A[15:11] must be ‘00000’ to access the configuration
port.
The Configuration Ports base address is relocatable on even-byte boundaries; i.e., A0 = ‘0’.
At power-up the Configuration Ports base address is determined by the SYSOPT pin programming. To
relocate the Configuration Ports base address after power-up, first write the lower address bits of the
BIT NO.
