(4) Receive packet ready interrupts (EP1, EP2)
These interrupts are generated when the respective EP has received an appropriate data packet from the USB
bus and the local MCU can read that data.

Description (conditions, responses, etc.)
Receive packet ready
interrupt generation
ML60851D
The receive packet ready bit of the corresponding EP
status register (EPnSTAT) is asserted during data
reception when the EOP of the data packet has been
received and the data has been stored without error in the
corresponding FIFO. The end of a packet is recognized
when an EOP has arrived in the cases of both full packets
and short packets.
An interrupt is generated at this time, if the corresponding
receive packet ready interrupt enable bit has been
asserted.
(EOP: End of packet)
End of receive packet ready
interrupt
Local MCU (firmware)
After the number of bytes in the receive FIFO data
(EPnFIFO) indicated by the corresponding receive byte
count register (EPnRXCNT) has been read, write a “1” into
the respective receive packet ready bit of the end point
packet ready register (PKTRDY). (This bit is reset when a
'1' is written in this bit.)
The following table outlines the relationship between ML60851D registers and packet ready interrupt generation
during EP1 or EP2 receive (host to device communication) operation.
