Однократнопрограммируемый телевизионный процессор. В даташите есть ссылка на manual programming, но документик в иннете найти не могу.
Прошу помочь либо ссылкой на документ, либо инфой, где подробно можно почитать о
IN-SYSTEM PROGRAMMING INTERFACE
A serial programming interface is available for late OTP
programming. The interface is based on the IEEE1149
(JTAG) standard, but only two instructions are utilized.
Table 42 shows which port pins are used for ISP.
Care should be taken during system design to ensure the
pins used for serial programming do not cause conflict with
the application circuit. It is advised to dedicate the port pins
(P2.1, P2.2, P2.3 and P2.4) to ISP, and not use them in
application.
However, if it is necessary to use them in application then
they must be assigned as output.
The device is placed in ISP mode using the RESET pin.
Pin P0.2 must be held HIGH during ISP mode. Power to
the device during ISP may be sourced either from the
application or from an external source. Ground reference
between the programmer and the target should be
common.
For further details, refer to the “In-System Programming
Application Note SPG/AN01008”.
