Access in multiplexed P-interface mode:
A logical 1 disables the corresponding interrupt as described in the ISTA-register.
A masked interrupt is stored internally and reported in ISTA immediately if the mask is
released. However, an SFI interrupt is also reported in ISTA if masked. In this case no
interrupt is generated. When writing register MASK while ISTA indicates a non masked
interrupt INT is temporarily set into the inactive state.

Synchronous transfer Interrupt; The SIN interrupt is enabled if at least one
synchronous transfer channel (A and/or B) is enabled via the STCR:TAE,
TBE bits. The SIN interrupt is generated when the access window for the P
opens. After the occurrence of the SIN interrupt the P can read and/or write
the synchronous transfer data registers (STDA, STDB). The SIN bit is reset
by reading ISTA.
Synchronous transfer Overflow; The SOV interrupt is generated if the P fails
to access the data registers (STDA, STDB) within the access window. The
SOV bit is reset by reading ISTA.
