The total amount of FIFO storage allocated to enabled endpoints must not exceed 2462 bytes.
IN: input for the USB host (ISP1181A transmits); OUT: output from the USB host (ISP1181A 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.
programmable FIFO sizes.
The following bits in the Endpoint Configuration Register (ECR) affect FIFO
allocation:
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.
