Value R/W Description
3 to 0 PIPESEL[3:0] 0000 R/W Pipe Window Select
Selects the pipe number corresponding to the
PIPECFG, PIPEBUF, PIPEMAXP, and PIPEPERI
registers which data is written to or read from.
0000: No pipe selected
0001: PIPE1
0010: PIPE2
0011: PIPE3
0100: PIPE4
0101: PIPE5
0110: PIPE6
0111: PIPE7
1000: PIPE8
1001: PIPE9
Other than above: Setting prohibited
Selecting a pipe number through these bits allows
writing to and reading from the PIPECFG,
PIPEBUF, PIPEMAXP, and PIPEPERI registers
that correspond to the selected pipe number.
When PIPESEL = 0000, 0 is read from all of the bits
in PIPECFG, PIPEBUF, PIPEMAXP, PIPEERI and
PIPEnCTR. Writing to these bits is invalid.
21.3.32 Pipe Configuration Register (PIPECFG)
PIPECFG is a register that specifies the transfer type, buffer memory access direction, and
endpoint numbers for PIPE1 to PIPE9. It also selects continuous or non-continuous transfer mode,
single or double buffer mode, and whether to continue or disable pipe operation at the end of
transfer.
This register is initialized by a power-on reset. Only the TYPE[1:0] bits are initialized by a USB
bus reset.
