15.3
15.3.1
The SPI is disabled in all stop modes, regardless of the settings before executing the STOP instruction.
During stop2 mode, the SPI module will be fully powered down. Upon wake-up from stop2 mode, the SPI
module will be in the reset state. During stop3 mode, clocks to the SPI module are halted. No registers are
affected. If stop3 is exited with a reset, the SPI will be put into its reset state. If stop3 is exited with an
interrupt, the SPI continues from the state it was in when stop3 was entered.
15.4
The SPI has five 8-bit registers to select SPI options, control baud rate, report SPI status, and for
transmit/receive data.
Refer to the direct-page register summary in the
assignments for all SPI registers. This section refers to registers and control bits only by their names, and
a Freescale-provided equate or header file is used to translate these names into the appropriate absolute
addresses.
15.4.1
This read/write register includes the SPI enable control, interrupt enables, and configuration options.

SPI in Stop Modes
SPI Control Register 1 (SPIC1)
SPI Interrupt Enable (for SPRF and MODF) — This is the interrupt enable for SPI receive buffer full (SPRF)
and mode fault (MODF) events.
0 Interrupts from SPRF and MODF inhibited (use polling)
1 When SPRF or MODF is 1, request a hardware interrupt
SPI System Enable — Disabling the SPI halts any transfer that is in progress, clears data buffers, and initializes
internal state machines. SPRF is cleared and SPTEF is set to indicate the SPI transmit data buffer is empty.
0 SPI system inactive
1 SPI system enabled
SPI Transmit Interrupt Enable — This is the interrupt enable bit for SPI transmit buffer empty (SPTEF).
0 Interrupts from SPTEF inhibited (use polling)
1 When SPTEF is 1, hardware interrupt requested
