FUNCTION
25 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 41 shows which port pins are used for ISP.
Care should be taken during system design to ensure the
pinsused forserialprogramming donotcause conflict with
theapplicationcircuit.Itisadvisedtodedicatetheportpins
(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.
