4 / 26 page Usage Notes The LC66E2316 was created for program development, product evaluation, and prototype development for products based on the LC6623XX Series microcontrollers. Keep the following points in mind when using this product. 1. After a reset The RES pin must be held low for an additional 3 instruction cycles after the oscillator stabilization period has elapsed. Also, the port output circuit types are set up during the 9 instruction cycles immediately after RES is set high. Only then is the program counter set to 0 and program execution started from that location. (The port output circuits all revert to the open-drain type during periods when RES is low.) 2. Notes on LC6623XX evaluation The high end of the EPROM area (locations 3FF0H to 3FFFH) are the option specification area. Option specification data must be programmed for and loaded into this area. The Sanyo specified cross assembler for this product is the program LC66S.EXE. Also, insert JMP instructions so that user programs do not attempt to execute addresses that exceed the capacity of the mask ROM, and write zeros (00H) to areas (other than 3FF0H to 3FFFH) that exceed the actual capacity of the mask ROM. 3. Always apply an opaque seal to the window on the LC66E2316 package when actually using the device. Main differences between the LC66E2316, LC66P2316, and LC6623XX Series Note: * Although the microcontroller will remain in hold mode if the RES pin is set low while it is in hold mode, always use the reset start sequence (after switching HOLD from low to high, switch RES from low to high) when clearing hold mode. Also not that a current of about 100 µA flows from the RES pin when it is low. This increases the hold mode current drain by about 100 µA. See the data sheets for the individual products for details on other differences.
