(5) Transmit packet ready interrupts (EP1, EP2, EP3, EP4 bulk, EP5 bulk)
These interrupts are generated when it is possible for the local MCU to write the data packet to be sent to the
USB bus from the corresponding EP.

ML60852
Description (conditions, responses, etc.)
(1) In the case of bulk transfer and interrupt transfer
When the respective EP has been set for transmission,
the transmit packet ready bit of the corresponding EP
(bit D1 of EPnSTAT) is de-asserted when it is possible
to write the transmit data into the FIFO.
At this time, an interrupt is generated if the
corresponding EP transmit packet ready interrupt
enable bit (INTENBL1) has been asserted.
For the second and subsequent packets, in addition to
this condition, before the interrupt is generated, it is
necessary for an ACK response to come from the host
for the packet that has just been sent.
(1) In the case of bulk transfer and interrupt transfer
After the one packet of the corresponding EP transmit
data has been written in EPnTXFIFO, write a “1” into the
corresponding transmit packet ready bit (bit D1 of
EPnSTAT). This puts the ML60852 in a state in which it
can transmit the data and the
INTR
pin is de-asserted at
the same time.
Even when the number of bytes in the write data is less
than the maximum packet size, it is possible to end the
pocket transmission by writing a “1” into the transmit
packet ready status bit.
