3.1.2 Outline of Operation Modes
There are single-chip and single-boot modes. Which mode is selected depends on the device’s
pin state after a reset.
Single-chip mode:
Single-boot mode:
The device normally operations in this mode. After a reset, the device starts
executing the internal memory program.
This mode is used to rewrite the internal flash memory by serial transfer
(UART).
After a reset, internal boot program starts up, executing an on-board rewrite
program.
