2.1 Protect Usage
2.1.1 Overview of the protect usage
'Protect' is a function that causes a value held in a register to be unchanged even when a program runs
away. The following is an overview of the protect usage:
(1) Registers affected by the protect function
(2) Protect register
The registers affected by the protect function are:
The values in registers (1) through (3) cannot be changed in write-protect state. To change values in
the registers, put the individual registers in write-enabled state.
Figure 2.1.1 shows protect register.
(a) System clock control registers 0, 1 (addresses 0006
(b) Processor mode registers 0, 1 (addresses 0004
