clocked out of the TSC2046.
It is recommended that the processor mask the interrupt
PENIRQ
is associated with whenever the processor sends a
control byte to the TSC2046. This prevents false triggering
of interrupts when the
PENIRQ
output is disabled in the
cases discussed in this section.
16 Clocks-per-Conversion
The control bits for conversion n + 1 can be overlapped with
conversion n to allow for a conversion every 16 clock cycles,
as shown in Figure 11. This figure also shows possible serial
communication occurring with other serial peripherals be-
tween each byte transfer from the processor to the con-
verter. This is possible, provided that each conversion com-
pletes within 1.6ms of starting. Otherwise, the signal that is
captured on the input sample-and-hold may droop enough to
affect the conversion result. Note that the TSC2046 is fully
powered while other serial communications are taking place
during a conversion.
