P89LPC932A1
8-bit microcontroller with accelerated two-clock 80C51 core
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.
7.17.6 Timer overow toggle output
Timers 0 and 1 can be congured to automatically toggle a port output whenever a timer
overow occurs. The same device pins that are used for the T0 and T1 count inputs are
also used for the timer toggle outputs. The port outputs will be a logic 1 prior to the rst
timer overow when this mode is turned on.
7.18 RTC/system timer
The P89LPC932A1 has a simple RTC that allows a user to continue running an accurate
timer while the rest of the device is powered-down. The RTC can be a wake-up or an
interrupt source. The RTC is a 23-bit down counter comprised of a 7-bit prescaler and a
16-bit loadable down counter. When it reaches all logic 0s, the counter will be reloaded
again and the RTCF ag will be set. The clock source for this counter can be either the
CCLK or the XTAL oscillator, provided that the XTAL oscillator is not being used as the
CPU clock. If the XTAL oscillator is used as the CPU clock, then the RTC will use CCLK as
its clock source. Only power-on reset will reset the RTC and its associated SFRs to the
default state.
