(in-circuit emulator) tools (z9036900zem) to make programming and debugging easy and convenient. zilog developer studio (zds) provides easy code generation and program management. for code development, zilog offers its specialized application program interface (api) for osd. api deals directly with proper sequencing and timing when interfacing with hardware, shielding the user application program from tedious and error prone details. the z8933200zco, an osd evaluation board (zosd) is used to synchronize the emulator with a video display. refer to the diagram below for a suggested code development environment. the z9036100zdp is the adapter used to program the z90361 otp. zilog also offers the z8933200tsc protopak to verify code on a television. related products develop code on pc z90369 z90361 z90369 in-circuit emulation kit zosd board converts to video display download code to z90369 ice chip program the z90361 otp review code on tv display z9037x dual scan tv controller for progressive scan z9035x advanced tv controller with 64 kwords of rom, programmable palette, and cursor z9036x advanced tv controller with 32 kwords of rom z86129 closed caption decoder (ccd) z86229 closed caption decoder (ccd) with second i 2 c address select z86131 auto time set z86130 smart v-chip z86230 smart v-chip with second i 2 c address select
