Note 1 Programmable pull-up resisters of Port 0 can be attatched in nibble units (P00-03, P04-07).
(*) When in parallel interface mode, PB0-PB7 output format is CMOS, regardless of any selected option.
Note: Connect as follows to reduce noise on VDD and increase the back-up time.
VSS1, VSS2 and VSS3 must be connected together and grounded.
The voltage of Port 7 should be fixed.
Example 1 : In hold mode, during backup, port output ‘H’ level is supplied from the back-up capacitor.
Example 2 : During backup in hold mode output is not held high and its value in unsettled.
