Crystal
Oscillator
Anti-shock
Controlled with serial data command from micro-
computer. When not used, General purpose input/
output terminal 7. set it as the input terminal and open
it by connecting to 0 V, or set it as the output terminal
and open it.
PLL
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
Be sure to supply the same potential to each power terminal. (VVDD, ADAVDD, VDD, LVDD, RVDD, XVDD)
Terminal witch is controlled by the power terminal (VDD5V) for a microcomputer interface :
CE(61 pin), CL(62 pin), DI(63 pin), DO(64 pin), WRQ(65 pin), RES(66 pin), DRF(67 pin)
