6.5. SPIF223A UART and SPI Interface Select:
SPIF223A have supported 2 IO interface: UART and SPI. Then,
it could be configured by pin21 (UART_SPI_Sel)
UART_SPI_Sel : 0 Using UART interface.
UART_SPI_Sel : 1 Using SPI interface.

6.6. SPIF223A Device Mode or Host :
SPIF223A have supported both dirction : SerialATA to ATA host
bridge and ATA to SerialAT host bridge. Then, we could use pin20
(H_D_Sel).
H_D_Sel : 0 Serial ATA device to ATA host mode
(Connecting to ATA HDD)..
H_D_Sel : 1 ATA device to Serial ATA host mode.
(Connecting to Serial ATA HDD).
6.7. SPIF223A ATA Device Mode Select:
When SPIF223A have been choice to H_D_Sel as 1, it will use as
ATA device mode. For ATA device, SPIF223A could support
www.mDaasttaeSr,hselaevte4Uan.cdoCmable select. It could be configured by :
6.8. SPIF223A Serial ATA bus Tri-state Feature:
SPIF223A have supported Serial ATA bus Tri-state feature under
UART_SPI_SEL as low. It could help to design a combo interface
or multi-interface product.
SPI_CLK : Low
Serial ATA bus Hi-Z.
SPI_CLK : High
Serial ATA bus normal feature.
6.9. SPIF223A ATA bus Tri-state Feature:
SPIF223A have supported ATA bus tri-state by pin 38 (SPI_EN). If
SPI_EN# is low, SPIF223A will enable ATA bus Tri-state. If
SPI_EN# is high, SPIF223A will go into normal function to accept
ATA bus access. (For this mode, UART_SPI_Sel must be low.)
SPI_EN# : Low
ATA bus Tri-State
SPI_EN#: High ATA bus normal feature.
