12.3.13 Packet Enable Register 0i (PKTE0i)
The number of transmit data is written in PKTE0i after writing transmit data in EPDR0i. Then
transmit data becomes valid and data is transmitted by the next IN token. Data is not transmitted
only by writing data in EPDR0i.
The number of data bytes written in EPDR0i must match the number of transmit data bytes to be
written in PKTE0i.
12.3.14 Packet Enable Register 2 (PKTE2)
The number of transmit data is written in PKTE2 after writing transmit data in EPDR2. Then
transmit data becomes valid and data is transmitted by the next IN token. Data is not transmitted
only by writing data in EPDR2.
The number of data bytes written in EPDR2 must match the number of transmit data bytes to be
written in PKTE2.
12.3.15 Packet Enable Register 3 (PKTE3)
The number of transmit data is written in PKTE3 after writing transmit data in EPDR3. Then
transmit data becomes valid and data is transmitted by the next IN token. Data is not transmitted
only by writing data in EPDR3.
The number of data bytes written in EPDR3 must match the number of transmit data bytes to be
written in PKTE3.
