P89LPC933/934/935/936
8-bit microcontroller with accelerated two-clock 80C51 core
8.28.10 Hardware activation of the boot loader
The boot loader can also be executed by forcing the device into ISP mode during a
power-on sequence (see the P89LPC933/934/935/936 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 vector is changed, it will no longer
point to the factory preprogrammed ISP boot loader 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.
8.29 User configuration bytes
Some user-configurable features of the P89LPC933/934/935/936 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. Please see the
P89LPC933/934/935/936 User manual for additional details.
8.30 User sector security bytes
There are eight User Sector Security Bytes on the P89LPC933/934/935/936 device. Each
byte corresponds to one sector. Please see the P89LPC933/934/935/936 User manual for
additional details.

A/D converter
9.1 General description
The P89LPC935/936 have two 8-bit, 4-channel multiplexed successive approximation
analog-to-digital converter modules sharing common control logic. The P89LPC933/934
have a single 8-bit, 4-channel multiplexed analog-to-digital converter and an additional
DAC module. A block diagram of the A/D converter is shown in Figure 23. Each A/D
consists of a 4-input multiplexer which feeds a sample-and-hold circuit providing an input
signal to one of two comparator inputs. The control logic in combination with the SAR
drives a digital-to-analog converter which provides the other input to the comparator. The
output of the comparator is fed to the SAR.
9.2 Features and benefits
Two (P89LPC935/936) 8-bit, 4-channel multiplexed input, successive approximation
A/D converters with common control logic (one A/D on the P89LPC933/934).
Four result registers for each A/D.
Six operating modes:
Fixed channel, single conversion mode.
Fixed channel, continuous conversion mode.
Auto scan, single conversion mode.
Auto scan, continuous conversion mode.
Dual channel, continuous conversion mode.
Single step mode.
Four conversion start modes:
Timer triggered start.
