22.0 Detailed Register Descriptions
The first page of 128 locations of memory contains the control registers. The control registers are accessed
independent of the setting of the memory select bits when in multiplexed mode by setting external address bit
A7 to 0. In non-multiplexed mode the control registers are accessed with A7,A8 and A9 set to 1 (as described
in Section 5.1). The control registers and their addresses are listed in Table 20.
