Register and PIO
Table 58 and Figure 47 describe the ATAPI register and the PIO
data transfer timing.
Figure 47 displays the REG and PIO data transfer timing. Note
that ATAPI_ADDR pins include A1-3, ATAPI_CS0, and
ATAPI_CS1. Alternate ATAPI port ATAPI _ADDR pins
include ATAPI_A0A, ATAPI_A1A, ATAPI_A2A, ATAPI_CS0,
and ATAPI_CS1. Note that an alternate ATAPI_D0-15 port bus
is ATAPI_D0-15A

1 ATAPI timing register setting should be programmed with a value that guarantees parameter compliance with the ATA ANSI specification for the ATA device mode of
operation.
