Description added
When DMA transfer is enabled (EP2T1 = 1 and EP2T0 = 0 or 1
in UDMAR) at endpoint 2, it is not possible to clear OUTFIFO in
EP2. It is necessary to disable DMA transfer (EP2T1 = 0 and
EP2T0 = 0 in UDMAR) before clearing the FIFO.
Description amended
The HD64F2218, HD64F2218U, and HD64F2218CU have 12
kbytes of on-chip high-speed static RAM. The HD6432217,
HD64F2211, HD64F2211U, and HD64F2211CU have 8 kbytes
of on-chip high-speed static RAM. The HD6432210 and
HD6432210S have 4 kbytes of on-chip high-speed static RAM.
The RAM is connected to the CPU by a 16-bit data bus,
enabling one-state access by the CPU to both byte data and
word data.
EP2T0 set to 0 or 1 in UDMAR), it is not possible to
clear the data in the FIFO by writing 1 to EP2CLR. To
clear the data in the FIFO, disable DMA transfers (clear
EP2T1 and EP2T0 in UDMAR to 0) and then write 1 to
EP2CLR.
