... Microchip Technology Inc. PIC16F627A/628A/648A 1.0 PROGRAMMING THE PIC16F627A/628A/648A The PIC16F627A/628A/648A is programmed using a serial method. The Serial mode will allow the PIC16F627A/628A/648A to be programmed while in the user’s system. This allows for increased design flexibility. This programming specification applies to PIC16F627A/628A/648A devices in all packages. ...

... Legend Input Output Power Note 1: In the PIC16F627A/628A/648A, the programming high voltage is internally generated. To activate the Programming mode, high voltage needs to be applied to MCLR input. Since the MCLR is used for a level source, this means that MCLR does not draw any significant current. ...

... PIC16F627A/628A/648A The optional 16-bit data word will either be an input to, ® output from the PIC microcontroller, depending on the command. Load Data commands will be input, and Read Data commands will be output. The 16-bit data word only contains 14 bits of data to conform to the 14-bit program memory word. The 14 bits are centered within the 16-bit word, padded with a leading and trail- ing zero ...
