2.16 Pipe Configuration Register
Remarks
* When "PIPESEL=0000", "0" is read from all of the bits of the related registers noted above. When "PIPESEL=0000", write to
the pipe related to Address68H-6EH register is invalid.

Bit
♦ Pipe window selection register [PIPESEL]
PIPESEL
Pipe window selection
Pipe1 - Pipe9 should be written to using the PIPESEL, PIPECFG, PIPEBUF, PIPEMAXP, PIPEPERI, PIPExCTR,
PIPExTRE and PIPExTRN registers. After selecting the pipe using the PIPESEL register, write to the pipe functions
using the PIPECFG, PIPEBUF, PIPEMAXP and PIPEPERI registers. The PIPExCTR, PIPExTRE and PIPExTRN
registers can be written to separately from the pipe selection specified with the PIPESEL register, with no relation
between them.

If the software writes "0001" to "1001" to this bit, the controller displays the pipe information and the setup value
corresponding to the registers from address H68 to H6C. After pipe specification writing of this bit, the value written by
the software in address H68 to H6C is reflected in the corresponding pipe transfer method.
If the software writes "0000" to this bit, the controller setss all "0" in the register from address H68 to H6C. Using
software to write to address H68 to H6C is invalid.
