372 / 478 page  PIC16(L)F1946/47 DS41414D-page 372 2010-2012 Microchip Technology Inc. 28.2 Low-Voltage Programming Entry Mode The Low-Voltage Programming Entry mode allows the PIC® Flash MCUs to be programmed using VDD only, without high voltage. When the LVP bit of Configuration Words is set to ‘1’, the low-voltage ICSP programming entry is enabled. To disable the Low-Voltage ICSP mode, the LVP bit must be programmed to ‘0’. Entry into the Low-Voltage Programming Entry mode requires the following steps: 1. MCLR is brought to VIL. 2. A 32-bit key sequence is presented on ICSPDAT, while clocking ICSPCLK. Once the key sequence is complete, MCLR must be held at VIL for as long as Program/Verify mode is to be maintained. If low-voltage programming is enabled (LVP = 1), the MCLR Reset function is automatically enabled and cannot be disabled. See Section 6.4 “MCLR” for more information. The LVP bit can only be reprogrammed to ‘0’ by using the High-Voltage Programming mode. 28.3 Common Programming Interfaces Connection to a target device is typically done through an ICSP™ header. A commonly found connector on development tools is the RJ-11 in the 6P6C (6-pin, 6 connector) configuration. See Figure 28-2. FIGURE 28-2: ICD RJ-11 STYLE CONNECTOR INTERFACE Another connector often found in use with the PICkit™ programmers is a standard 6-pin header with 0.1 inch spacing. Refer to Figure 28-3.
