8.18.9
Transmit interrupts with double buffering enabled (Modes 1, 2 and 3)
Unlike the conventional UART, in double buffering mode, the Tx interrupt is generated
when the double buffer is ready to receive new data.
8.18.10
The 9th bit (bit 8) in double buffering (Modes 1, 2 and 3)
If double buffering is disabled TB8 can be written before or after SBUF is written, as
long as TB8 is updated some time before that bit is shifted out. TB8 must not be
changed until the bit is shifted out, as indicated by the Tx interrupt.
If double buffering is enabled, TB8 must be updated before SBUF is written, as TB8
will be double-buffered together with SBUF data.
8.19 Analog comparators
One analog comparator is provided on the P89LPC901. Two analog comparators are
provided on the P89LPC902 and P89LPC903 devices. Comparator operation is such
that the output is a logical one (which may be read in a register) when the positive
input is greater than the negative input (selectable from a pin or an internal reference
voltage). Otherwise the output is a zero. The comparator may be congured to cause
an interrupt when the output value changes.
The connections to the comparator are shown in Figure 19. Note: Not all possible
comparator congurations are available on all three devices. Please refer to the Logic
diagrams in Section 6 “Logic symbols” on page 12. The comparator functions to
VDD = 2.4 V.
When the comparator is rst enabled, the comparator output and interrupt ag are not
guaranteed to be stable for 10 microseconds. The comparator interrupt should not be
enabled during that time, and the comparator interrupt ag must be cleared before
the interrupt is enabled in order to prevent an immediate interrupt service.
When a comparator is disabled the comparator’s output, COx, goes HIGH. If the
comparator output was LOW and then is disabled, the resulting transition of the
comparator output from a LOW to HIGH state will set the comparator ag, CMFx.
This will cause an interrupt if the comparator interrupt is enabled. The user should
therefore disable the comparator interrupt prior to disabling the comparator.
Additionally, the user should clear the comparator ag, CMFx, after disabling the
comparator.
