TFST—Transfer Status
0 = No data transfer is currently in progress.
1 = Data transfer is currently in progress.
SLAS—Slave Select
Reading this bit returns the current value of the SS exclusive-OR’d with the SSPO bit.
0 = SS pin is Low, if SSPO = 0, SS pin is High if SSPO = 1 (SS is asserted).
1 = SS pin is High, if SSPO = 0, SS pin is Low if SSPO = 1 (SS is deasserted).

internal state.
SCKI—Serial Clock Input
This bit reflects the state of the serial clock pin.
0 = The SCK input pin is Low
1 = The SCK input pin is High
SDI—Serial Data Input
This bit reflects the state of the serial data input (MOSI or MISO depending on the
bit).
0 = The serial data input pin is Low.
1 = The serial data input pin is High.
ESPISTATE—ESPI State Machine
Indicates the current state of the internal ESPI State Machine. This information is intended
for manufacturing test. The state values may change in future hardware revisions and are
not intended to be used by a software driver.
