32.2.26 Pipe Window Select Register (PIPESEL)
Pipes 1 to 9 should be set using registers PIPESEL, PIPECFG, PIPEMAXP, PIPEPERI, PIPEnCTR, PIPEnTRE, and
PIPEnTRN.
After selecting the pipe using the PIPESEL register, functions of the pipe should be set using registers PIPECFG,
PIPEMAXP, and PIPEPERI. PIPEnCTR, PIPEnTRE, and PIPEnTRN can be set regardless of the pipe selection in the
PIPESEL register.
PIPESEL[3:0] Bits (Pipe Window Select)
The PIPESEL[3:0] bits select the pipe number corresponding to registers PIPECFG, PIPEMAXP, and PIPEPERI which
data are written to or read from.
Selecting a pipe number through the PIPESEL[3:0] bits allows writing to and reading from registers PIPECFG,
PIPEMAXP, and PIPEPERI which correspond to the selected pipe number.
When PIPESEL[3:0] = 0000b, 0 is read from all of the bits in registers PIPECFG, PIPEMAXP, and PIPEPERI. Writing
to these bits is invalid.
