24.14 IN Pipe management
The Pipe must be configured first.
When the Host requires data from the device, the firmware has to determine first the IN mode to
use using the INMODE bit:
INMODE = 0. The INRQX register is taken in account. The Host controller will perform
(INRQX+1) IN requests on the selected Pipe before freezing the Pipe. This mode avoids to
have extra IN requests on a Pipe
INMODE = 1. The USB controller will perform infinite IN request until the firmware freezes the
Pipe
The IN request generation will start when the firmware clear the PFREEZE bit.
Each time the current bank is full, the RXIN and the FIFOCON bits are set. This triggers an inter-
rupt if the RXINE bit is set. The firmware can acknowledge the USB interrupt by clearing the
RXIN bit. The Firmware read the data and clear the FIFOCON bit in order to free the current
