Command Definitions
When low voltage is applied to the V
PP
pin, the contents of the
command register default to 00H. Placing high voltage on the V
PP
pin enables read/write operations. Device operations are selected
by writing specific data patterns into the command register. Table 9
defines these 89C536/538 register commands. Table 10 defines the
bus operations of 89C536/538.
