Functional description
Interrupt Mask Register (IMASK)
Table 16: Interrupt Mask Register
Interrupt Clear Register (ICLR)
Table 17: Interrupt Clear Register
FIFO Threshold Register (FTHR)
Table 18: FIFO threshold register
This register is used to program values such as 1 (flush), 16 or 32 (DMA burst) or any greater value
up to 2032 for interrupt driven data transfer. Note that for proper DMA operation, ‘threshold’ must be
greater than or equal to the DMA burst size (MICR[BSIZE]).

Holds the FIFO threshold value
threshold = TH * 16
Reserved
Each IMASK bit set to ‘1’ enables the corresponding interrupt source bit in the status
register (SR)
Reserved
Each ICLR bit written with a ‘1’ clears the corresponding interrupt source bit in the
status register (SR). Writing a ‘0’ has no effect
Reserved
Reserved
Threshold value in 16-byte increments.

Not Empty:
1 = Force threshold to 1 (TH is ignored)
