Specifications of LPC47N227TQFP

• Lead Free Status / RoHS Status: Not Compliant

CR0D
CR0D can only be accessed in the configuration state and after the CSR has been initialized to 0DH.
This register is read only. CR0D contains the LPC47N227 Device ID. The default value of this register
after power up is 5AH on VCC POR.
CR0E
CR0E can only be accessed in the configuration state and after the CSR has been initialized to 0EH.
This register is read only. CR0E contains the current LPC47N227 Chip Revision Level starting at 00H.
CR0F
CR0F can only be accessed in the configuration state and after the CSR has been initialized to 0FH.
CR0F 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.
