FIFO Ready Flag
Regardless of set values of DMAEN and

data amount matches the asserting
condition set in DMACR[2:0], and
otherwise, read as 1.

FIFO Ready Interrupt Flag
0: No interrupt
[Clearing condition]
Write 0 after reading FRDYI = 1.
(Writing 1 is invalid)
1: Interrupt requested
[Setting condition]
When remained FIFO data does not match
the assert condition set in DMACR while
DMAEN = 1 and FRDYIE = 1.
Note: FRDYI will be set on the setting
condition after clearing. To clear it,
disable the flag setting by FRDYIE in
INTCR2.
