22.3.9
Interrupt Enable Register 2 (IER2)
IER2 enables the interrupt requests of interrupt flag register 2 (IFR2). When an interrupt flag is set
to 1 while the corresponding bit of each interrupt is set to 1, an interrupt request is sent to the
CPU. The interrupt vector number is determined by the contents of interrupt select register 2
(ISR2).

22.3.10 EP0i Data Register (EPDR0i)
EPDR0i is an 8-byte transmit FIFO buffer for endpoint 0. EPDR0i holds one packet of transmit
data for control-in. Transmit data is fixed by writing one packet of data and setting EP0iPKTE in
the trigger register. When an ACK handshake is returned from the host after the data has been
transmitted, EP0iTS in interrupt flag register 0 is set. This FIFO buffer can be initialized by means
of EP0iCLR in the FCLR register.
