There are two memory MATs: user MAT and user boot MAT. The dedicated registers/parameters
are allocated for each operating mode and MAT selection. The correspondence of operating modes
and registers/parameters for use is shown in table 20.3.
Table 20.3 Registers/Parameters and Target Modes
Notes: 1. The setting is required when programming or erasing the user MAT in user boot mode.
20.3.1
The programming/erasing interface registers are described below. They are all 8-bit registers that
can be accessed only in bytes. These registers are initialized by a reset or in hardware standby
mode.
