4-1. Internal operation

Since the floppy

disk controller

is contained

within the

2.5" floppy disk drive unit and directly interfaced with the
bus line, data line and control

signals are directly

con-

nected.

So, only the power-on-reset

signal generation

circuit and

the amp's 5VC (+5V) supply regulator circuit are provided

for circuit.

REST

Fig. 1 shows the reset circuit and Fig. 2 shows its timings.

R5 is acharge

current regulating resistor C3 which is used

for pullup and delay. D4 is a diode which is used to bypass
the charge in C3 to VCC line when VCC is off.
