Dual-Port RAM
7.2.1 Command Register Examples
To perform a complete reset of the CP, the value $8001 should be written to the CR. Fol-
lowing this command, the CR will return the value $0000 in two clocks.
To execute an ENTER HUNT MODE command to SCC3, the value $0381 should be written
to the CR. While the command is executing, the CR will return the value $0381. When the
command has been completely executed, the CR will return the value $0380.
7.2.2 Command Execution Latency
The worst-case command execution latency is 120 clocks. The typical command execution
latency is about 40 clocks.
7.3 DUAL-PORT RAM
The CPM has 2560 bytes of static RAM configured as dual-port memory. The dual-port RAM
memory map is shown in Figure 7-2, and a block diagram is shown in Figure 7-3.
7-8
0 = The CP is ready to receive a new command.
1 = The CR contains a command that the CP is currently processing. The CP clears
this bit at the end of the command execution or after reset.
