Port x Drive x Control Registers
Function
:
These registers control the features of the four devices connected to the two ports. All four registers are
identical and control the features of only one device. The Port 0 Drive 0 Control Register (44h-47h)
controls the features of the master drive attached to the primary port. The Port 0 Drive 1 Control Register
(48h-4Bh) controls the features of the slave drive attached to the primary port. The Port 1 Drive 0 Control
Register (4Ch-4Fh) controls the features of the master drive attached to the secondary port. The Port 1
Drive 1 Control Register (50h-53h) controls the features of the slave drive attached to the secondary port.
The command timing controls only affect 16-bit and 32-bit accesses.
Calculations (refer to Table 4-4):
CMD ON TIME programmed value = (DIOR#/DIOW# 16-bit min+29) / 30ns clock - 1, after
removing all digits to the right of the decimal point (see Table 4-4).
CMD OFF TIME programmed value = ((Cycle Time minimum – (CMD ON TIME programmed value
+ 1) * 30ns + 29)) / 30ns clock -1, after removing all digits to the right of the decimal point (see Table
4-4).
CMD ON TIME = Bits [12:8] of Port x Control x Registers , which are the registers of Configuration
Space 44h-54h.
CMD OFF TIME = Bits [4:0] of Port x Control x Registers , which are the registers of Configuration
Space 44h-54h.
