36.3.5 I/O Pin Characteristics
The I/O pins comply with the JEDEC LVTTL and LVCMOS specification and the high- and low level input and output
voltage limits reflect or exceed this specification.
Table 36-71. I/O pin characteristics.
Notes:
1.
The sum of all IOH for PORTA and PORTB must not exceed 100mA.
The sum of all IOH for PORTC must not exceed 200mA.
The sum of all IOH for PORTD and pins PE[0-1] on PORTE must not exceed 200mA.
The sum of all IOH for PE[2-3] on PORTE, PORTR and PDI must not exceed 100mA.
2. The sum of all I
OL for PORTA and PORTB must not exceed 100mA.
The sum of all IOL for PORTC must not exceed 200mA.
The sum of all IOL for PORTD and pins PE[0-1] on PORTE must not exceed 200mA.
The sum of all IOL for PE[2-3] on PORTE, PORTR and PDI must not exceed 100mA.
