8-bit microcontroller with on-chip CAN
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.
