EP02 control register 3 (EP02CON3) [address 001C16]

Bit name

Bit symbol

At reset

Function

H/W

S/W

–: State remaining

Buffer 1 enable bit

Not used

When the selected endpoint is IN, writing “1” to this bit

makes the transmitting data a set state (SIE is possible

to read).

When the selected endpoint is OUT, writing “1” to this

bit makes data reception possible (SIE is possible to

write).

In double buffer mode this bit is valid.

Write “0” when writing.

“0” is read when reading.
