I've checked the ADuC7024 SPI timing in Master Mode. With the MMR settings below I get the scope trace shown below. The MOSI signal measured changing 89ns after a SCLK falling edge. According to Table 7 and Figure 7 on page 13 of the ADuC7024 data sheet (Rev D) this timing figure, tDAV (data output valid after SCLOCK edge) has a max value of 25ns.
POWCON = 0x00000000
PLLCON = 0x00000001
SPICON = 0x00001283 (phase = 0, polarity = 0)
SPIDIV = 0x00000005
Top trace : MOSI (data = 0x9F)
Bottom trace : SCLOCK
As an aside, note 1 for Table 7 says "..CD bits in the PLLCON...". The CD bits are actually in POWCON.
