Description
External Data Bus. 32-Bit bi-directional data bus for data transfer. The KS8695P
also supports 8-bit and 16-bit data bus widths.
SDRAM Chip Select: Active low chip select pins for SDRAM. The KS8695P
supports up to two SDRAM banks. One SDCSN output is provided for each bank.
SDRAM Row Address Strobe: Active low. The row address strobe pin for SDRAM.
SDRAM Column Address Strobe: Active low. The column address strobe pin for
SDRAM.
SDRAM Write Enable: Active low. The write enable signal for SDRAM.
SDRAM Data Input/Output Mask: Data input/output mask signals for SDRAM. The
SDQM is sampled high and is an output mask signal for write accesses and an
output enable signal for read accesses. Input data are masked during a write cycle.
The SDQM0/1/2/3 correspond to DATA[7:0], DATA[15:8], DATA[23:16] and
DATA[31:24], respectively.
External I/O Device Chip Select: Active low. Three external I/O banks are provided
for external memory mapped I/O operations. Each I/O bank stores up to 16KB.
The ECSNx signals indicate which of the three I/O banks is selected.
External Wait: Active low. This signal is asserted when an external I/O device or a
ROM/SRAM/FLASH bank needs more access cycles than those defined in the
corresponding control register.
ROM/SRAM/FLASH Chip Select: Active low. The KS8695P can access up to two
external ROM/SRAM/FLASH memory banks. The RCSN pins can be controlled to
map the CPU addresses into physical memory banks.
