System communication to and from the ESCC is accomplished using the 
ESCC register set. There are 17 Write registers and 16 Read registers. Many of the fea-
tures on the ESCC are enabled through a new register in the ESCC: Write Register 7
Prime (WR7’). This new register can be accessed if bit 0 or WR15 is set to 1.
page 10 lists the Write registers and a brief description of their functions.
11 lists the Read Registers.
