7.2.6
This register reflects the UART interrupt status, which is encoded by different interrupt sources into 3
bits.
Bit 7, 6:
Bit 5, 4:
Bit 3: In 16450 mode, this bit is 0. In 16550 mode, both bit 3 and 2 are set to a logical 1 when a time-
out interrupt is pending.
Bit 2, 1:
below.
Bit 0: This bit is a logical 1 if there is no interrupt pending. If one of the interrupt sources has occurred,
this bit will be set to a logical 0.
Interrupt Status Register (ISR) (Read only)
These two bits are set to a logical 1 when UFR bit 0 = 1.
These two bits are always logic 0.
These two bits identify the priority level of the pending interrupt, as shown in the table
