Data read/written depends on the value written to the SPR prior to
the access of this register (see
Table 11
)
Table 10: 950 Specific Registers
Register access notes:
Note 1: Requires LCR[7] = 0
Note 2: Requires ACR[7] = 0
Note 3: Requires that last value written to LCR was not 0xBF
Note 4: To read this register ACR[7] must be = 0
Note 5: To read this register ACR[6] must be = 0
Note 6: Requires ACR[7] = 1
Note 7: Only bits 0 and 1 of this register can be written
Note 8: To read this register ACR[6] must be = 1
Note 9: This register acts as a window through which to read and write registers in the Indexed Control Register set
