IO1WT
I/O window 1 wait addition in 16-bit accesses
0 : No additional wait state
1 : Adds 1 wait state
6
W1_IOWS
I/O window 1 wait addition in 8-bit accesses
0 : No additional wait state
1 : Adds 1 wait state
5
IO1_CS16MD
I/O window 1 IOCS16 source
0 : Value of the IO1DSZ bit
1 : CF_IOIS16# signal from the card
4
IO1DSZ
I/O window 1 access data size
0 : 8 bits
1 : 16 bits
This bit has no function when the IO1_CS16MD bit is set to 1.
3
IO0WT
I/O window 0 wait addition in 16-bit accesses
0 : Without additional wait state
1 : Adds 1 wait state
2
W0_IOWS
I/O window 0 wait addition in 8-bit accesses
0 : No additional wait state
1 : Adds 1 wait state
1
IO0_CS16MD
I/O window 0 IOCS16 source
0 : Value of the IO0DSZ bit
1 : CF_IOIS16# signal from the card
0
IO0DSZ
I/O window 0 access data size
0 : 8 bits
1 : 16 bits
This bit has no function when the IO0_CS16MD bit is set to 1.
