CS
I
Chip selection input with pull-high resistor
When the CS is logic high, the data and command, read from or
written to the HT1620 are disabled. The serial interface circuit is
also reset. But if the CS is at logic low level and is input to the CS
pad, the data and command transmission between the host con-
troller and the HT1620 are all enabled.
41
RD
I
READ clock input with pull-high resistor
Data in the RAM of the HT1620 are clocked out on the falling
edge of the RD signal. The clocked out data will appear on the
DATA line. The host controller can use the next raising edge to
latch the clocked out data.
42
WR
I
WRITE clock input with pull-high resistor
Data on the DATA line are latched into the HT1620 on the rising
edge of the WR signal.

may cause substantial damage to the device. Functional operation of this de-
vice at other conditions beyond those listed in the specification is not implied and prolonged
exposure to extreme conditions may affect device reliability.
