Section 4 Operating Modes
4. Operating Modes
4.1 Operating Mode Selection
This LSI has five operating modes that are selected by pins MD2 to MD0 and FWE. The mode setting pins should not be
changed during operation of this LSI, and only the setting combinations shown in table 4.1 should be used.
The PV_CC1 power supply voltage must be within the range shown in table 4.1.

There are two MCU operating modes: MCU single-chip mode and MCU expanded mode.
Modes in which the flash memory can be programmed are boot mode, user boot mode and user program mode (the two
on-board programming modes) and programmer mode in which programming is performed with an EPROM programmer
(a type which supports programming of this device).
For details, see section 24, ROM (SH7058S) and section 25, ROM (SH7059).
