4.2.6 Interrupt Status Register (ISR) (Read only)

This register reflects the UART interrupt status, which is encoded by different interrupt sources into 3
bits.

0 if interrupt pending
Interrupt Status bit 0
Interrupt Status bit 1
Interrupt Status bit 2
FIFOs enabled
FIFOs enabled

Bit 7, 6: These two bits are set to a logical 1 when UFR bit 0 = 1.

Bit 5, 4: These two bits are always logic 0.

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: These two bits identify the priority level of the pending interrupt, as shown in the table 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.
