The INT# interrupt output changes according to the operating mode and enhanced features setup.
Table 2
and 3
summarize the operating behavior for the transmitter and receiver.
INT# Ouput
2.5
The 784 includes an on-chip oscillator (XTAL1 and XTAL2). The crystal oscillator provides the system clock to
the Baud Rate Generators (BRG) in each of the 8 UARTs, the 16-bit general purpose timer/counter and
internal logics. XTAL1 is the input to the oscillator or external clock buffer input with XTAL2 pin being the
output. For programming details, see
“Section 2.6, Programmable Baud Rate Generator” on page 8
.
The on-chip oscillator is designed to use an industry standard microprocessor crystal (parallel resonant,
fundamental frequency with 10-22 pF capacitance load, ESR of 20-120 ohms and 100ppm frequency
tolerance) connected externally between the XTAL1 and XTAL2 pins (see
Figure 3
). Alternatively, an external
clock can be connected to the XTAL1 pin to clock the internal 8 baud rate generators for standard or custom
rates. Typically, the oscillator connections are shown in
Figure 3
. For further reading on oscillator circuit please
see application note DAN108 on EXAR’s web site.
