P89LPC9102/9103/9107
8-bit microcontrollers with two-clock accelerated 80C51 core
Power-on detect
Brownout detect
Watchdog timer
Software reset
UART break character detect reset (P89LPC9103/9107).
For every reset source, there is a ag in the Reset Register, RSTSRC. The user can read
this register to determine the most recent reset source. These ag bits can be cleared in
software by writing a logic 0 to the corresponding bit. More than one ag bit may be set:
During a power-on reset, both POF and BOF are set but the other ag bits are
cleared.
For any other reset, previously set ag bits that have not been cleared will remain set.
8.16 Timers 0 and 1
The P89LPC9102 has two general purpose timer/counters which are similar to the
standard 80C51 Timer 0 and Timer 1. These timers have ve operating modes (modes 0,
1, 2, 3, and 6). Modes 0, 1, and 2 are the same for both Timers. Mode 3 is different.
The P89LPC9103/9107 has two general purpose timers which are similar to the standard
80C51 Timer 0 and Timer 1. These timers have four operating modes (modes 0, 1, 2, and
3). Modes 0, 1, and 2 are the same for both Timers. Mode 3 is different.
8.16.1 Mode 0
Putting either Timer into Mode 0 makes it look like an 8048 Timer, which is an 8-bit
Counter with a divide-by-32 prescaler. In this mode, the Timer register is congured as a
13-bit register. Mode 0 operation is the same for Timer 0 and Timer 1.
8.16.2 Mode 1
Mode 1 is the same as Mode 0, except that all 16 bits of the timer register are used.
8.16.3 Mode 2
Mode 2 congures the Timer register as an 8-bit counter with automatic reload. Mode 2
operation is the same for Timer 0 and Timer 1.
8.16.4 Mode 3
When Timer 1 is in Mode 3 it is stopped. Timer 0 in Mode 3 forms two separate 8-bit
counters and is provided for applications that require an extra 8-bit timer. When Timer 1 is
in Mode 3 it can still be used by the serial port as a baud rate generator.
8.16.5 Mode 6 (P89LPC9102/9107)
In this mode, the corresponding timer can be changed to a PWM with a full period of
256 timer clocks.
