Bit 7: FLOW - Flow Control
This bit is used to control pin IORDY according to the status of 8-byte Data FIFO. It should be set
high for 8-bit DRAM and low for 4-bit DRAM. FLOW is de-activated by chip reset or host reset.
Bit 6: TSYNC - Test Synchronization Control
When this bit is high, the detected/inserted DSP data sync can be monitored from CLKO (pin 13).
Bit 5, 4: Reserved
Bit 3: CLKOS - Pin CLKO Select
When CLKOS is low, CLKO pin supplies clock signal of one-half the crystal frequency. When this
bit CLKOS is high, CLKO pin supplies normal crystal frequency.
Bit 2, 1: Reserved
Bit 0: XTALD2 - Crystal Divided by 2
The internal clock frequency is half of crystal frequency if this bit is high.
VER - Version Register - (read 1Ah)
This register is used to hold the version number. The current version of W88111AF is 1Bh. The
