LC7442, 7442E
Initial Settings
RES pin: reset
This pin must be held low when power is first applied.
Internal control registers
The table below lists the states of the registers following a reset.
Register
State
SBY
H
KOUT–A, KOUT–B
L
PLL6
L
PLL5
L
PLL4
H
PLL3
H
Registers other than the above are not initialized by a reset.
Serial Data Interface
Serial input format
The first 8 bits of data following SDE going low specify an address, and the next 8 bits are register data for that address.
The last 8 bits of data are transferred to the incremented address.
The address can be re-specified after switching SDE from low to high to low again (
).
Since the PLL clock is not used for serial data transfer, data transfers can be performed when SBY is high. However,
data cannot be transferred to registers that are initialized by a reset.
Since there is no way to confirm that the transferred data was latched correctly, we recommend refreshing this data
periodically.
No. 4412-18/22
Power supply (DVDD, AVDD, OVDD, KVDD)
RES
tD: At least a few microseconds.
Notes: H: VDD level
L: VSS level
These states are set even if SBY = H.
Since all system operations are stopped at this time, the data held in external
memory cannot be retained.
