26.3 Hardware Conditions to Enter the ISP Mode

The boot loader can be executed by holding ALEB high, RST/
V
as +9V, and ACLK(optional) with OSC. 1.8432MHz. The
PP
ISP function uses following pins: TxD, RxD, ALEB, ACLK and
RST/V
.

Erase the data in your target MCU before programming it.
Verify whether or not a device is in an erased or unprogrammed state.
This button enables you to place new data from the memory buffer into the target device.
Read the data in the target MCU into the buffer for examination. The checksum will be displayed
on the checksum box.
Assures that data in the device matches data in the memory buffer. If your device is secured, a
verification error is detected.
Secures devices so that their content can no longer be examined or modified.

Erase & Program & Verify
If selected with check mark, the security locking is performed after erasure.
Connect a MCU in your target Board with displaying as "Connected" in the status box. Users have
