Description
Slot Assign Error
0: Indicates that no slot assign error occurs
1: Indicates that a slot assign error occurs
A slot assign error occurs when the specifications in
SITDAR, SIRDAR, and SICDAR overlap.
If a slot assign error occurs, the SIOF does not transmit
data to the SIOFTxD pin and does not receive data from
the SIOFRxD pin. Note that the SIOF does not clear the
TXE bit or RXE bit in SICTR at a slot assign error.

Frame Synchronization Error
0: Indicates that no frame synchronization error occurs
1: Indicates that a frame synchronization error occurs
A frame synchronization error occurs when the next
frame synchronization timing appears before the previous
data or control data transfers have been completed.
If a frame synchronization error occurs, the SIOF
performs transmission or reception for slots that can be
transferred.

This bit is valid when the TXE bit or RXE bit in SICTR
is 1.
When 1 is written to this bit, the contents are cleared.
If the issue of interrupts by this bit is enabled, an
SIOF interrupt is issued.
This bit is valid when the TXE or RXE bit in SICTR is
1.
When 1 is written to this bit, the contents are cleared.
Writing 0 to this bit is invalid.
If the issue of interrupts by this bit is enabled, an
SIOF interrupt is issued.
