Caution:
There is a restriction on the use of indexed addressing for EEPROM read operations.
When the base address of an indexed read of an EEPROM location is within the
EEPROM address range ($0400 to $04FF), the read may not be successful.
e.g. LDA (BASE ADDRESS), X – may not give the correct result when the base
address is in the range $0400 to $04FF. However, if the base address is outwith the
EEPROM address range, the read operation will be successful. This restriction applies
to all operations capable of using indexed addressing.
(1) Typical values are at midpoint of voltage range and at 25
°C only.
(2) All IDD measurements taken with suitable decoupling capacitors across the power supply to suppress the
transient switching currents inherent in CMOS designs. RUN and WAIT IDD: measured using an external
square-wave clock source (fOSC = 3.58 MHz); all inputs0.2V from rail; no DC loads; maximum load on outputs
50pF (20pF on OSC2). WAIT IDD: only the timer system and DMG active; current varies linearly with the OSC2
capacitance. STOP and WAIT IDD: all ports congured as inputs, VIL = 0.2 V, VIH = VDD 0.2 V. STOP IDD:
measured with OSC1 = VSS.
