The total amount of FIFO storage allocated to enabled endpoints must not exceed 2462 bytes.
IN: input for the USB host (ISP1181B transmits); OUT: output from the USB host (ISP1181B receives). The data flow direction is
determined by bit EPDIR in the Endpoint Configuration Register.
9.2 Endpoint FIFO size
The size of the FIFO determines the maximum packet size that the hardware can
support for a given endpoint. Only enabled endpoints are allocated space in the
shared FIFO storage, disabled endpoints have zero bytes.
Table 5
lists the
programmable FIFO sizes.
The following bits in the Endpoint Configuration Register (ECR) affect FIFO
allocation:
Endpoint enable bit (FIFOEN)
Size bits of an enabled endpoint (FFOSZ[3:0])
Isochronous bit of an enabled endpoint (FFOISO).
Remark:
Register changes that affect the allocation of the shared FIFO storage
among endpoints must
not
be made while valid data is present in any FIFO of the
enabled endpoints. Such changes will render
all
FIFO contents
undefined
.
