4.2.13
Serial Interrupt Mask 2 Register
The Serial Interrupt Mask Registers 1 and 2 enable the generation of a CPU interrupt. Writing
a '1' to the bit “SIRQ_ENx” enables the generation of a CPU interrupt and enables the
corresponding bit in the Serial Interrupt Pending Registers 1 and 2.
4.2.14
Serial Interrupt Polarity 1 Register
The Serial Interrupt Polarity 1 Register bits define the polarity of their corresponding serial
interrupt. A '1' written to the required bit position results in an active high sensitivity of the
corresponding interrupt and vice versa.
4.2.15
Serial Interrupt Polarity 2 Register
The Serial Interrupt Polarity 2 Register bits define the polarity of their corresponding serial
interrupt. A '1' written to the required bit position results in an active high sensitivity of the
corresponding interrupt and vice versa.
