Product specification

P8xCE598

4. ALE is activated every six oscillator periods. During an external data memory access one ALE pulse is skipped.

5. See Section 7.1, Table 3 for EA operation. For P83CE598 microcontrollers specified with the option ‘ROM-code

protection’, the EA pin is latched during reset and is ‘don't care’ after reset, regardless of whether the ROM-code

protection is selected or not.

6. Pin 78, REF:

a) Selection of input respectively output dependent of CAN Control Register bit 5 (CR.5; see Section 13.5.3

Table 32).

b) If the internal reference is used, then REF should be connected to AVSS via a capacitor with a value of ≥ 10 nF.

c) After an external reset (RST = HIGH) the internal 1⁄2AVDD source is activated and, REF is a reference output.

d) If the CAN-controller is in the reset state, e.g. after an external reset, then the 1⁄2AVDD source is switched off

during Power-down mode.

7. CAN Bus line:

a) CRX0 level > CRX1 level is interpreted as a logic 1 (recessive).

b) CRX0 level < CRX1 level is interpreted as a logic 0 (dominant).

8. The level of AVREF+ must be higher than that of AVREF−.
