Webbbit 7-6 URXISEL<1:0>: Receive Interrupt Mode Selection bits 11 = Interrupt flag bit is set when receive buffer is full (i.e., has 4 data characters) 10 = Interrupt flag bit is set when receive buffer is 3/4 full (i.e., has 3 data characters) 0x = Interrupt flag bit is set when a character is received WebbThis feature is called the Interrupt Stack Table (IST). There can be up to 7 IST entries per CPU. The IST code is an index into the Task State Segment (TSS). The IST entries in the TSS point to dedicated stacks; each stack can be a different size. An IST is selected by a non-zero value in the IST field of an interrupt-gate descriptor. minigolf blue city
