Section 4 Operating Modes
4.1 Operating Mode Selection
The SH7058 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 the SH7058, 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 23, ROM.
