Programming Information
FIGURE 27. MICROPROCESSOR READ TIMING (RDMODE = 0)
NOTES:
10. All configuration registers have a master/slave architecture. The master registers are clocked by WR. The slave registers are clocked by CLK.
11. The master registers are writable and cleared by a hard reset. All master registers are located in the SC µP block.
12. The slave registers are readable and cleared by either a hard or soft reset. Refer to the table to determine location of slave registers.
13. Partition indirect address space into pages of 256 words.
14. Decode indirect address <9:8> to determine page, (3 used).
15. Indirect address<14:10> are not used.
16. Indirect address<15> determines access type. 1=read; 0=write.
8. Consecutive accesses to the same address require a 4 clock synchronized update to occur before beginning the next accesses.
9. Different direct address locations can be accessed without having to wait for a 4 clock synchronized update to occur.
