Philips Electronics N.V. 2001. All rights reserved.
Bits RESET, RESUME, EOT and SOF are cleared upon reading the Interrupt
Register. The endpoint bits (EP0OUT to EP14) are cleared by reading the associated
Endpoint Status Register.
Bit BUSTATUS follows the USB bus status exactly, allowing the firmware to get the
current bus status when reading the Interrupt Register.
SETUP and OUT token interrupts are generated after ISP1161’s DC has
acknowledged the associated data packet. In bulk transfer mode, the ISP1161’s DC
will issue interrupts for every ACK received for an OUT token or transmitted for an IN
token.
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 Pseudo Start-Of-Frame (PSOF) interrupt, enabled via bit IEPSOF in the Interrupt
Enable Register. If a Start-Of-Frame is lost, PSOF interrupts are generated every
1 ms. This allows the firmware to keep data transfer synchronized with the host. After
3 missed SOF events the ISP1161’s DC will enter ‘suspend’ state.
An alternative way of handling isochronous data transfer is to enable both the SOF
and the PSOF interrupts and disable the interrupt for each isochronous endpoint.
