Control Register (SPCR)
SPCR sets the operating mode. If the MSTR and MODFEN bits are changed while the function of
this module is enabled by setting the SPE bit to 1, subsequent operations cannot be guaranteed.

Receive Interrupt Enable
Enables or disables generation of receive interrupt
requests (SPRI) when the number of receive data
units in the receive buffer (SPRX) is equal to or
greater than the specified receive buffer data
triggering number and the SPRF flag in SPSR is set
to 1.

Function
Enable
Setting this bit to 1 enables the module function.
When the MODF bit in the status register (SPSR) is
1, the SPE bit cannot be set to 1 (see section 16.4.6,
Error Detection). Setting the SPE bit to 0 disables
the module function, and initializes a part of the
module function (see section 16.4.7, Initialization).
