6.3 CS Registers
Table 6-2 shows the CS module registers and their address offsets. The base address can be found in the
device-specific data sheet.
All CS registers are password protected except Status Register (CSSTAT) and Interrupt Flag Register
(CSIFG). The password that is defined in CSKEY controls access to the CS registers. To enable write
access to the CS registers, write the correct password to CSKEY. To disable write access, write any
incorrect password to CSKEY.
