CHAPTER 22 USB FUNCTION CONTROLLER (USBF)
Set these bits to 1 when writing transmit data to the UF0BIn register has been
completed. When these bits are set to 1, the FIFO is toggled as soon as possible, the
BKInNK bit is set to 1, and data is transferred.
These bits control the FIFO on the CPU side.
If the BKInCC bit of the UF0FIC0 register is set to 1 and then these bits are set to 1
(counter of UF0BIn register = 0), a Null packet (with a data length of 0) is transmitted.
If data exists in the UF0BIn register and if these bits are set to 1 (counter of UF0BIn
register ≠ 0), and if the FIFO is not full, a short packet is transmitted.
If the FIFO on the CPU side of the UF0BIn register becomes full as a result of DMA, with
the PIO or BKInT bit set to 1, the hardware starts data transmission even if these bits are
not set to 1.
If the FIFO on the CPU side of the UF0BIn register becomes full as a result of DMA, with
the BKInT bit cleared to 0, be sure to set these bits to 1 (see 22.6.3 (3) UF0 EPNAK
register (UF0EN)).
Set this bit to 1 to transmit data of the UF0E0W register. When this bit is set to 1, the
EP0NKW bit is set to 1 and data is transferred.
If the EP0WC bit of the UF0FIC0 register is set to 1 and if this bit is set to 1 (counter of
UF0E0W register = 0 and bit 1 of UF0EPS0 register = 1), a Null packet (with a data
length of 0) is transmitted.
If data exists in the UF0E0W register and if this bit is set to 1 (counter of UF0E0W
register ≠ 0 and bit 1 of the UF0EPS0 register = 1), and if the FIFO is not full, a short
packet is transmitted.
1: Transmit a short packet.
0: Do not transmit a short packet (default value).
1: Transmit a short packet.
0: Do not transmit a short packet (default value).
