P89LPC952/954
8-bit microcontroller with 10-bit ADC
7.16.1 Reset vector
Following reset, the P89LPC952/954 will fetch instructions from either address 0000H or
the Boot address. The Boot address is formed by using the boot vector as the high byte of
the address and the low byte of the address = 00H.
The Boot address will be used if a UART break reset occurs, or the non-volatile Boot
Status bit (BOOTSTAT.0) = 1, or the device is forced into ISP mode during power-on (see
P89LPC952/954
User’s Manual). Otherwise, instructions will be fetched from address
0000H.
7.17 Timers/counters 0 and 1
The P89LPC952/954 has two general purpose counter/timers which are upward
compatible with the standard 80C51 Timer 0 and Timer 1. Both can be congured to
operate either as timers or event counters. An option to automatically toggle the T0 and/or
T1 pins upon timer overow has been added.
In the ‘Timer’ function, the register is incremented every machine cycle.
In the ‘Counter’ function, the register is incremented in response to a 1-to-0 transition at its
corresponding external input pin, T0 or T1. In this function, the external input is sampled
once during every machine cycle.
Timer 0 and Timer 1 have ve operating modes (Modes 0, 1, 2, 3 and 6). Modes 0, 1, 2
and 6 are the same for both Timers/Counters. Mode 3 is different.
7.17.1 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.
7.17.2 Mode 1
Mode 1 is the same as Mode 0, except that all 16 bits of the timer register are used.
7.17.3 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.
7.17.4 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.
7.17.5 Mode 6
In this mode, the corresponding timer can be changed to a PWM with a full period of
256 timer clocks.
