CGR
(clock gate for read) Input:
C GR
is an input signal that enables/disables incrementing of the
internal read address pointer. When
CGR
is low, the read address pointer is incremented in
synchronization with the RCK read clock, and when high, incrementing is stopped. Therefore time axis
expansion can be easily implemented without stopping the read clock by using
CGR
.
WAS
(write address set and jump) Input:
WAS
is an input signal that initiates write jump address input
when
WRS
is high and jumps to the previously input write jump address when
WRS
is low. The falling
edge of this input signal is detected, and either a write jump address input is initiated or a jump to the
previously input write jump address is executed on the first WCK cycle following the fall of
WAS
.
WAD (write jump address) Input:
WAD is the input pin for the write jump address. The 14/15 bits of
the write jump address are read in sequentially from the high order bit, starting at the WCK cycle (when
WRS
was high) in which
WAS
was set low.

RAS
(read address set and jump) Input:
RAS
is an input signal that initiates read jump address input
when
RRS
is high and jumps to the previously input read jump address when
RRS
is low. The falling edge
of this input signal is detected, and either the read jump address input is initiated or the jump to the
previously input read jump address is executed on the first WCK cycle following the fall on
RAS
.
RAD (read jump address) Input:
RAD is the input pin for the read jump address. The 14/15 bits of the
write jump address are read in sequentially from the high order bit, starting at the RCK cycle (when
R R S
was high) in which
R AS
was set low.
