ATA Electrical Specifications
This section describes the electrical information of the Parallel ATA module compliant with ATA/ATAPI-6
specification.
Parallel ATA module can work on PIO/Multi-Word DMA/Ultra DMA transfer modes. Each transfer mode
has different data transfer rate, Ultra DMA mode 4 data transfer rate is up to 100 MB/s. Parallel ATA
module interface consist of a total of 29 pins, Some pins act on different function in different transfer
mode. There are different requirements of timing relationships among the function pins conform with
ATA/ATAPI-6 specification and these requirements are configurable by the ATA module registers.
Below defines the AC characteristics of all the interface signals on all data transfer modes.
