Bit #  
Name  
Function  
Type  
TTL/ST(1)  
bit0  
RB0/INT  
Bi-directional I/O port/external interrupt. Can be software programmed for  
internal weak pull-up.  
TTL/ST(3)  
bit1  
RB1/RX/DT  
RB2/TX/CK  
RB3/CCP1  
RB4/PGM  
Bi-directional I/O port/ USART receive pin/synchronous data I/O. Can be  
software programmed for internal weak pull-up.  
TTL/ST(3)  
bit2  
Bi-directional I/O port/ USART transmit pin/synchronous clock I/O. Can be  
software programmed for internal weak pull-up.  
TTL/ST(4)  
bit3  
Bi-directional I/O port/Capture/Compare/PWM I/O. Can be software pro-  
grammed for internal weak pull-up.  
TTL/ST(5)  
bit4  
Bi-directional I/O port/Low voltage programming input pin. Wake-up from  
SLEEP on pin change. Can be software programmed for internal weak  
pull-up. When low voltage programming is enabled, the interrupt on pin  
change and weak pull-up resistor are disabled.  
RB5  
bit5  
bit6  
TTL  
Bi-directional I/O port/Wake-up from SLEEP on pin change. Can be soft-  
ware programmed for internal weak pull-up.  
TTL/ST(2)  
RB6/T1OSO/T1CKI  
Bi-directional I/O port/Timer1 oscillator output/Timer1 clock input. Wake up  
from SLEEP on pin change. Can be software programmed for internal weak  
pull-up.  
TTL/ST(2)  
RB7/T1OSI  
bit7  
Bi-directional I/O port/Timer1 oscillator input. Wake up from SLEEP on pin  
change. Can be software programmed for internal weak pull-up.  
Legend: ST = Schmitt Trigger, TTL = TTL input  
Note 1: This buffer is a Schmitt Trigger input when configured as the external interrupt.  
Note 2: This buffer is a Schmitt Trigger input when used in serial programming mode.  
Note 3: This buffer is a Schmitt Trigger I/O when used in USART/synchronous mode.  
Note 4: This buffer is a Schmitt Trigger I/O when used in CCP mode.  
Note 5: This buffer is a Schmitt Trigger input when used in low voltage program mode.
