Section 22 Flash Memory
There are several operating modes for accessing the flash memory. Respective operating modes,
registers, and parameters are assigned to the user MAT and user boot MAT. The correspondence
between operating modes and registers/parameters for use is shown in table 22.3.
Table 22.3 Registers/Parameters and Target Modes
Notes: 1. The setting is required when programming or erasing the user MAT in user boot mode.
22.7.1
The programming/erasing interface registers are 8-bit registers that can be accessed only in bytes.
These registers are initialized by a reset.
(1)
FCCS monitors errors during programming/erasing the flash memory and requests the on-chip
program to be downloaded to the on-chip RAM.
