UPIO_SPI pass-through control register. These bits
map the serial interface signals to the UPIO pins, allow-
ing the DAS to drive other devices at CPOUT or DVDD
voltage levels, depending on the SV_ bit setting found
in the UPIO_CTRL register. Individual bits are provided
to set only the desired UPIO inputs to the SPI pass-
through mode. This mode becomes active when
CS is
driven high to complete the write to this register, and
remains active as long as
CS stays high (i.e., multiple
pass-through writes are possible). The SPI pass-
through mode is deactivated immediately when
CS is
pulled low for the next DAS write.
The UPIO_ state (both before and after the SPI pass-
through mode) is set by the UP_MD<3:0> and LL_ bits.
When a UPIO is configured for SPI pass-through mode
and the
CS is high, UPR_, UPF_, and LL_ continue to
detect UPIO_ edges, which can still generate interrupts.
See Figure 19 for an SPI pass-through timing diagram.
UP4S: UPIO4 SPI pass-through-mode enable bit. A
logic 1 maps the inverted
CS signal to the UPIO4 pin.
Therefore, UPIO4 is low (near DGND) when SPI pass-
through mode is active, and is high (near DVDD or
CPOUT) when the mode is inactive. A logic 0 disables
the UPIO4 SPI pass-through mode. The power-on
default is 0.
UP3S: UPIO3 SPI pass-through-mode enable bit. A
logic 1 maps the SCLK signal to UPIO3 (directly with no
inversion), while a logic 0 disables the UPIO3 SPI pass-
through mode. The power-on default is 0.
UP2S: UPIO2 SPI pass-through-mode enable bit. A
logic 1 maps the DIN signal to UPIO2 (directly with no
inversion), while a logic 0 disables the UPIO2 SPI pass-
through mode. The power-on default is 0.
UP1S: UPIO1 SPI pass-through-mode enable bit. A
logic 1 maps the UPIO1 input signal to DOUT (directly
with no inversion), while a logic 0 disables the UPIO1
SPI pass-through mode. The power-on default is 0.
