Reset can be triggered from the following sources:
External reset pin (during power-up or if user congured via UCFG1. This option
must be used for an oscillator frequency above 12 MHz (P89LPC906).)
Power-on detect
Brownout detect
Watchdog Timer
Software reset
UART break character detect reset (P89LPC908).
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 ‘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.
8.15 Timers/counters 0 and 1
The P89LPC906/907/908 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. And additional PWM output mode, Mode 6, is provided on the P89LPC907.
8.15.1
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.
8.15.2
Mode 1
Mode 1 is the same as Mode 0, except that all 16 bits of the timer register are used.
8.15.3
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.
8.15.4
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 for
the P89LPC907 and P89LPC908.
8.15.5
Mode 6 (P89LPC907)
In this mode, the corresponding timer can be changed to a PWM with a full period of
256 timer clocks.
