CL RC632
6.3 Register Initialisation Files (Read/Write)
Register initialisation in the register address range from 10_hex to 2F_hex is done automatically during the
Initialising Phase (see 11.3), using the Start Up Register Initialisation File.
Furthermore, the user may initialise the CL RC632 registers with values from the Register Initialisation File
executing the LoadConfig-Command (see 18.7.1).
Notes:
• The Page-Register (addressed with 10_hex, 18_hex, 20_hex, 28_hex) is skipped and not initialised.
• Make sure, that all PreSet registers are not changed.
• Make sure, that all register bits that are reserved for future use (RFU) are set to 0.
6.3.1 START UP REGISTER INITIALISATION FILE (READ/WRITE)
The content of the E²PROM memory bock address 1 and 2 are used to initialise the CL RC632 registers
10_hex to 2F_hex during the Initialising Phase automatically. The default values written into the E²PROM during
production are shown chapter 6.3.2.
The assignment is the following:
E²PROM Byte Address
10_hex (Block 1, Byte 0)
11_hex
…
2F_hex (Block 2, Byte 15)
Register Address
10_hex
11_hex
…
2F_hex
