In isochronous mode, an interrupt is issued upon each packet transaction. The
firmware must take care of timing synchronization with the host. This can be done via
the loss of Start-Of-Frame (NOSOF) interrupt, enabled via bit IENOSOF in the
Interrupt Enable Register. If a Start-Of-Frame is lost, NOSOF interrupts are
generated every 1 ms. This allows the firmware to keep data transfer synchronized
with the host. After 3 missed SOF events the ISP1181 will enter ‘suspend’ state.
An alternative way of handling isochronous data transfer is to enable both the SOF
and the NOSOF interrupts and disable the interrupt for each isochronous endpoint.
14. Power supply
The ISP1181 is powered from a single supply voltage, ranging from 4.0 to 5.5 V. An
integrated voltage regulator provides a 3.3 V supply voltage for the internal logic and
the USB transceiver. This voltage is available at pin V
reg(3.3)
for connecting an
external pull-up resistor on USB connection D
+
. See
Figure 11
.
The ISP1181 can also be operated from a 3.0 to 3.6 V supply, as shown in
Figure 12
.
In that case the internal voltage regulator is disabled and pin V
reg(3.3)
must be
connected to V
CC
.
15. Crystal oscillator and LazyClock
The ISP1181 has a crystal oscillator designed for a 6 MHz parallel-resonant crystal
(fundamental). A typical circuit is shown in
Figure 13
. Alternatively, an external clock
signal of 6 MHz can be applied to input XTAL1, while leaving output XTAL2 open.
The 6 MHz oscillator frequency is multiplied to 48 MHz by an internal PLL. This
frequency is used to generate a programmable clock output signal at pin CLKOUT,
ranging from 3 to 48 MHz.
