In-System Programming (ISP)
The AT89LP2052/LP4052 offers a serial programming interface which may be used in place of
the parallel programming interface or to program the device while in system. In this document
serial programming and In-System Programming (ISP) refer to the same interface. ISP supports
the same command set as parallel programming. However, during ISP command bytes are
entered serially over the Serial Peripheral Interface (SPI) pins. The device connections are
shown in Figure 23-21. The ISP Enable User Fuse must be enabled through Parallel Program-
ming prior to entering the first ISP session. ISP itself may disable the ISP Fuse, however any
changes to the ISP fuses will not take affect until the device has been powered down and up
again. The programmer must take care not to accidentally disable the ISP Fuse as this will make
the device unprogrammable through the serial interface. Only Parallel Programming may re-
enable the fuse.
