SFR explanation for PIC16F628(1)

INDF ( Indirect addressing memory ) 00h,80h,100h,180h Same as PIC16F84A, PIC16F873 TMR0 ( Timer0 count register ) 01h,101h Same as PIC16F84A, PIC16F873 PCL ( Program counter Lower register ) 02h,82h,102h,182h Same as PIC16F84A, PIC16F873The program memory of PIC16F628 is 2K words. STATUS ( Status register ) 03h,83h,103h,183h Same as PIC16F84A, PIC16F873 FSR ( Indirect address register ) 05h,85h,105h,185h Same as PIC16F84A, PIC16F873 PORTn (Port register)/TRISn (Port mode set register) 05h,06h,106h/85h,86h,186h In case of PIC16F84A, it has five RA ports. In case of PIC16F628, it has eight RA ports. However, RA5 is only for input mode and it can't use as an output port. Some functions are multiplexed in each port, so some time the ports can't be use as I/O port. RA4 port is Open Drain type same as PIC16F84A and PIC16F873 so it will become only ground or open state. If you use it as output port, the power supply from the outside is required. The usage of PORT register and TRIS register is same as PIC16F84A, PIC16F873 PCLATH ( Program counter Upper register ) 0Ah,8Ah,10Ah,18Ah Same as PIC16F84A, PIC16F873The program memory of PIC16F628 is 2K words. INTCON ( Interruption Control register ) 0Bh,8Bh,10Bh,18Bh Same as PIC16F84A, PIC16F873 OPTION_REG ( Option register ) 81h,181h Same as PIC16F84A, PIC16F873 TMR1L, TMR1H ( Timer 1 Count register ) 0Eh, 0Fh Same as PIC16F873 T1CON ( Timer1 control register ) 10h Same as PIC16F873 TMR2 ( Timer 2 Count register ) 11h Same as PIC16F873 T2CON ( Timer 2 Control Register ) 12h Same as PIC16F873 CCPR1L,CCPR1H ( CCP1 register ) 15h, 16h Same as PIC16F873 CCP1CON ( CCP1 Control Register ) 17h Same as PIC16F873 PR2 ( PWM period register ) 92h Same as PIC16F873 RCSTA ( Receive Status and Control Register ) 18h Same as PIC16F873 TXSTA ( Transmit Status and Control Register ) 98h Same as PIC16F873 SPBRG ( Speed Baud Rate Generator Register ) 99h Same as PIC16F873
