When the signals driven by the device programmer are also used for the user system, the control circuit
shown in the figure below is required. The circuit enables or disables the programming connection depending
on the state of a jumper.

Function
Controls the operation mode of the MCU. For details, please refer to
chapter 8.4 "Boot ROM program execution and Operation mode
and ROM Configuration Block".
Some programming tools require quartz precise timing of the MCU.
For this reason, the on-chip quartz oscillator circuit must be used.
Some programming tools require a handshake signal to speed up
communicating with the MCU. Please refer to the datasheet about
the port recommended for handshaking.
Some programming tools require to control the reset line of the
MCU.
The USART is used for communication between the programming
tool and the MCU. The MCU detects automatically, which USART
from a predefined set of USARTs is connected to the programming
tool. Please refer to the datasheet for the USART channel numbers
that can be used for programing the MCU.
This external capacitor pin is used to stabilize the power supply.
Please refer to the datasheet for the recommended capacitance
values and types.
If the power is supplied from the user system, the device
programmer power supply does not need to be connected. In case
the device programmer supply is connected, please connect so that
the power supply of the user side is not short-circuited.
