Waveforms
Figure 18 shows the behavior of the LH7A400 when
coming out of Reset or Power On. Figure 19 shows exter-
nal reset timing, and Table 10 gives the timing parame-
ters. Figure 20 depicts signal timing following a Reset.
Figure 21 shows the recommended components for
the SHARP LH7A400 32.768 kHz external oscillator
circuit. Figure 22 shows the same for the 14.7456 MHz
external oscillator circuit. In both figures, the NAND
gate represents the internal logic of the chip.
