MODULATION USING SDIO_x PINS FOR RU/RD
For RU/RD bits = 11, the SDIO_1, SDIO_2, and SDIO_3 pins
are available for RU/RD. In this mode, modulation levels of 2, 4,
and 16 are available. Note that the serial I/O port can be used only
in 1-bit serial mode.

For the configuration in Table 15, each profile pin is dedicated
to a specific channel. In this case, the SDIO_x pins can be used
for the RU/RD function, as described in Table 16.
Four-Level Modulation Using SDIO Pins for RU/RD
For RU/RD bits = 11 (the SDIO_1 and SDIO_2 pins are avail-
able for RU/RD), the modulation level is set to 4. See Table 17
for pin assignments, including SDIO_x pin assignments.
For the configuration shown in Table 17, the profile (channel
word) register is chosen based on the 2-bit value presented to
Profile Pins [P1:P2] or [P3:P4].
For example, if PPC = 101, [P0:P1] = 11, and [P2:P3] = 01, the
contents of the Channel Word 3 register of Channel 0 are
presented to the output of Channel 0 and the contents of the
Channel Word 1 register of Channel 1 are presented to the
output of Channel 1. SDIO_1 and SDIO_2 provide the RU/RD
function.
16-Level Modulation Using SDIO Pins for RU/RD
The RU/RD bits = 11 (SDIO_1 available for RU/RD), and the
level is set to 16. See the pin assignments shown in Table 18.
For the configuration shown in Table 18, the profile (channel
word) register is chosen based on the 4-bit value presented to
Profile Pins [P0:P3]. For example, if PPC = X10 and [P0:P3] =
1101, then the contents of the Channel Word 13 register of
Channel 0 is presented to the output of Channel 0. The SDIO_1
pin provides the RU/RD function.
