P89LPC980/982/983/985
8-bit microcontroller with accelerated two-clock 80C51 core
Remark: Users who wish to use this loader should take precautions to avoid erasing the
1 kB sector that contains this bootloader. Instead, the page erase function can be used to
erase the first eight 64-byte pages located in this sector.
A custom bootloader can be written with the Boot Vector set to the custom bootloader, if
desired.
7.29.10 Hardware activation of the bootloader
The bootloader can also be executed by forcing the device into ISP mode during a
power-on sequence (see the P89LPC980/982/983/985 User manual for specific
information). This has the same effect as having a non-zero status byte. This allows an
application to be built that will normally execute user code but can be manually forced into
ISP operation. If the factory default setting for the boot is changed, it will no longer point to
the factory pre-programmed ISP bootloader code. After programming the flash, the status
byte should be programmed to zero in order to allow execution of the user’s application
code beginning at address 0000H.
7.30 User configuration bytes
Some user-configurable features of the P89LPC980/982/983/985 must be defined at
power-up and therefore cannot be set by the program after start of execution. These
features are configured through the use of the flash byte UCFG1 and UCFG2. Please see
the P89LPC980/982/983/985 User Manual for additional details.
7.31 User sector security bytes
There are four/eight User Sector Security Bytes on the P89LPC980/982/983/985. Each
byte corresponds to one sector. Please see the P89LPC980/982/983/985 User manual for
additional details.

ADC (P89LPC983/985)
8.1 General description
The P89LPC985 has a 10-bit, 8-channel multiplexed successive approximation
analog-to-digital converter modules. The P89LPC983 has a 10-bit, 4-channel multiplexed
successive approximation analog-to-digital converter modules. A block diagram of the
ADC is shown in Figure 20 “ADC block diagram”.
