Selection of masking of error interrupt signal (INTSREx (x = 0 to 3))
0 Masks error interrupt INTSREx (INTSRx is not masked).
1 Enables generation of error interrupt INTSREx (INTSRx is masked if an error occurs).
Set EOCmn = 0 in the CSI mode, simplified I²C mode, and during UART transmission.^Note
Set EOCmn = 1 during UART reception.

When the transfer end interrupt is selected, the interrupt is generated when all stop bits have been completely
transferred.
Set 1 bit (SLCmn1, SLCmn0 = 0, 1) during UART reception and in the simplified I²C mode.
Set no stop bit (SLCmn1, SLCmn0 = 0, 0) in the CSI mode.
Note When using CSI01 not with EOC01 = 0, error interrupt INTSRE0 may be generated.
Caution Be sure to clear bits 3, 6, and 11 to “0”. Be sure to set bit 2 to “1”.
