z Bit 7– ERROR: Error Interrupt Enable
0: Error interrupt is disabled.
1: Error interrupt is enabled.
Writing a zero to this bit has no effect.
Writing a one to this bit will clear the Error Interrupt Enable bit, which disables the Error interrupt.
z Bits 6:4 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always write these bits to
zero when this register is written. These bits will always return zero when read.
z Bit 3– SSL: Slave Select Low Interrupt Enable
0: Slave Select Low interrupt is disabled.
1: Slave Select Low interrupt is enabled.
Writing a zero to this bit has no effect.
Writing a one to this bit will clear the Slave Select Low Interrupt Enable bit, which disables the Slave Select Low
interrupt.
z Bit 2 – RXC: Receive Complete Interrupt Enable
0: Receive Complete interrupt is disabled.
1: Receive Complete interrupt is enabled.

interrupt.
z Bit 1 – TXC: Transmit Complete Interrupt Enable
0: Transmit Complete interrupt is disabled.
1: Transmit Complete interrupt is enabled.
Writing a zero to this bit has no effect.
Writing a one to this bit will clear the Transmit Complete Interrupt Enable bit, which disable the Transmit Complete
interrupt.
