Test chip SCC Register 3

The CFGREG3 Register characteristics are:

Purpose SMC CS6 and CS7 Register that controls the match and mask bits of CS6

and CS7. See Mask operation to define SMC chip select address ranges on

page 3-15. CS6 and CS7 are reserved, and the bits in this register are

reserved.

Usage constraints This register is reserved. Do not read from or write to this register.

Configurations Not applicable.

Attributes See Table 3-6 on page 3-13.

Figure 3-8 shows the bit assignments.

Figure 3-8 Test chip CFGREG3 Register bit assignments

Table 3-10 shows the bit assignments.

Test chip SCC Register 4

The CFGREG4 Register characteristics are:

Purpose Miscellaneous Configuration Register that enables you to read and write

test chip configuration settings.

Usage constraints CFGREG4[5:4] =

are reserved and must not be used. These bits

are valid only if CFGREG4[0] is

[23:16] - Reserved. Do not modify.

[15:8] SMC_ADDR_MATCH1_0 SMC CS4 address match of top 8 bits.

[7:0] SMC_ADDR_MASK1_0 SMC CS4 address mask of top 8 bits.
