IO Space Access time - Read/Write
The value written to this field specifies the minimum
‘number of HCLK cycles, minus 1’ that the data strobe,
MCDAENn
The data strobe assertion time is specified by (AI+1)
HCLK cycles. For example, if AI = 0x10, the data strobe
assertion time is 16 + 1 = 17 cycles of HCLK
IO space Hold time - Read/Write
The value written to this field specifies the minimum
‘number of HCLK cycles, minus 1’ between de-asserting
the data strobe, MCDAENn
strobe, MCADENn.
The Hold time is specified by (HI +1) HCLK cycles. For
example, if HI = 0xC, the Hold time is 12 + 1 = 13 cycles of
HCLK.
IO space setup time - Read/Write
The value written to this field specifies the ‘number of
HCLK cycles, minus 1’ that the address strobe,
MCADENn, is set up before assertion of the data strobe,
MCDAENn.
The Setup time is specified by (PI+1) HCLK cycles. For
example, if PI = 0x25, the Setup time is 37 + 1 = 38 cycles
of HCLK.
