2.1.4 Operation Modes and External Bus Operation
The MB89630 series of microcontrollers have the following three operation modes.
(1) Single-chip mode
(2) External-ROM mode
(3) External-access internal-ROM mode
The memory map for each mode is as follows:
*: MB89635 Address values. For the addresses of each product in the MB89630 series, see
2.1.1.
Fig. 2.7 Memory Maps in Various Modes
The mode that the device enters depends on the states of the device-mode pins and the contents of the
mode data fetched during the reset sequence. The relationship between the states and operations of the
device-mode pins is shown below.
The following functions are selected according to the mode-data setting conditions.
Note: Do not select the single-chip mode with the externally-fetched mode data.
