Interrupt Mask Bits
Each SCC interrupt event can generate an interrupt signal indication via
pin INT/INT. Each bit position of registers
corresponding interrupt event in the interrupt status registers
ISR0..ISR2. Masked interrupt events never generate an interrupt
indication via pin INT/INT.
bit = ’0’
bit = ’1’
Moreover, masked interrupt events are:
• not displayed in the interrupt status registers
• displayed in interrupt status registers
Note: After RESET, all interrupt events are masked. Undefined bits must
