CPU Data Bus. Bi-directional data bus,
synchronously transmitted with
CPU_CLK rising edge.
NOTE: as with all ports in the
ZL50110/11/14 device, CPU_DATA[0] is
the least significant bit (lsb).
CPU Address Bus. Address input from
processor to ZL50110/11/14,
synchronously transmitted with
CPU_CLK rising edge.
NOTE: as with all ports in the
ZL50110/11/14 device, CPU_ADDR[2] is
the least significant bit (lsb).
CPU Chip Select. Synchronous to rising
edge of CPU_CLK and active low. Is
asserted with CPU_TS_ALE. Must be
asserted with CPU_OE to
asynchronously enable the CPU_DATA
output during a read, including DMA
read.
CPU Write Enable. Synchronously
asserted with respect to CPU_CLK
rising edge, and active low. Used for
CPU writes from the processor to
registers within the ZL50110/11/14.
Asserted one clock cycle after
CPU_TS_ALE.
