12.4.3.2 Isochronous endpoints
12.5.1 Suspend conditions
12.5 ISP1362 Peripheral Controller suspend and resume
A DMA transfer to or from an isochronous endpoint can be terminated by any of the
following conditions (bit names refer to the DcDMAConfiguration register, see
and
Table 20.
The Peripheral Controller in the ISP1362 detects a USB suspend condition in either of the
following cases:
Bus-powered devices that are suspended must not consume more than 500 A of current.
This is achieved by shutting down the power to system components or supplying them
with a reduced voltage.
The steps leading the Peripheral Controller to the suspend state are as follows:
EOT condition
DcDMACounter register zero
1. In the event of no SOF for 3 ms, the Peripheral Controller in the ISP1362 sets
2. When the firmware detects a suspend condition (through IESUSP), it must prepare all

a. All the signals connected to the Peripheral Controller in the ISP1362 must enter
b. All the input pins of the Peripheral Controller in the ISP1362 must have a CMOS
bus. When bit BUSTATUS of the DcInterrupt register is logic 0, the USB bus has left
suspend mode and the process must be aborted. Otherwise, the next step can be
executed.
