Electrical and Thermal Characteristics
The MPC5200 ATA Host Controller design makes data available coincidentally with the active edge of the
WRITE strobe in PIO and Multiword DMA modes.
All ATA transfers are programmed in terms of system clock cycles (IP bus clocks) in the ATA Host
Controller timing registers. This puts constraints on the ATA protocols and their respective timing modes
in which the ATA Controller can communicate with the drive.
Faster ATA modes (i.e., UDMA 0, 1, 2) are supported when the system is running at a sufficient frequency
to provide adequate data transfer rates. Adequate data transfer rates are a function of the following:
The ATA clock is the same frequency as the IP bus clock in MPC5200. See the MPC5200 User Manual [1].

Write data is latched by the drive at the inactive edge of the WRITE strobe. This gives ample
setup-time beyond that required by the ATA-4 specification.
Data is held unchanged until the next active edge of the WRITE strobe. This gives ample
hold-time beyond that required by the ATA-4 specification.
