All ST7 devices are based on a com- mon industry-standard 8-bit core, featuring an en- hanced instruction set. The ST7LITE3 features FLASH memory with byte-by-byte In-Circuit Programming (ICP) and In- Application Programming (IAP) capability. Under software control, the ST7LITE3 device can be placed in WAIT, SLOW, or HALT mode, reduc- ing power consumption when the application is in idle or standby state. The enhanced instruction set and addressing modes of the ST7 offer both power and flexibility to software developers, enabling the design of highly Figure 1. General Block Diagram efficient and compact application code. In addition to standard 8-bit data management, all ST7 micro- controllers feature true bit manipulation, 8x8 un- signed multiplication and indirect addressing modes. For easy reference, all parametric data are located in section 13 on page 131. The devices feature an on-chip Debug Module (DM) to support in-circuit debugging (ICD). For a description of the DM registers, refer to the ST7 ICC Protocol Reference Manual. CLKIN OSC1 OSC2 VDD VSS RESET Int. 1% RC 1MHz PLL x 8 or PLL X4 Ext.

The contents of the I/O port DR registers are readable only in output configuration. In input configura- tion, the values of the I/O pins are returned instead of the DR register contents. 2. The bits associated with unavailable pins must always keep their reset value. 3. For a description of the DM registers, see the ST7 ICC Reference Manual. 11/173 1 11 Page
