CS Registers
3.4 CS Registers
The CS module registers are listed in Table 3-2 . The base address can be found in the device-specific
data sheet. The address offset is listed in Table 3-2 . The password defined in CSCTL0 controls access to
the CS registers. After the correct password is written in word mode, write access to the CS registers is
enabled. Write access is disabled by writing an incorrect password in byte mode to the CSCTL0 upper
byte.
NOTE: All registers have word or byte register access. For a generic register ANYREG , the suffix
"_L" ( ANYREG_L ) refers to the lower byte of the register (bits 0 through 7). The suffix "_H"
( ANYREG_H ) refers to the upper byte of the register (bits 8 through 15).
