Bus read/write operation 2
Data read cycle
Data write cycle
Ta = –20 to +75°C, V
DD
= 5V ±5%, GND = 0 V
Notes: For character display, HP is the number of dots in the horizontal direction per character,
and for graphics mode, HP is the number of bits shown on the display from each byte of display data.
f
OSC
is the oscillator frequency, in units of MHz.
All measurements are made at 1.5 V.
Parallel operation (master mode)
Ta = –20 to +75°C, V
DD
= 5V ±5%, GND = 0 V
Notes: With no loads on any of the output pins.
Measurements are made at 0.5 V
