To add on to my original question. my method of doing to ID verification is by transmitting two bytes of serial data, it has the 5 zeroes as the most significant bits while the 10 ID code bits are least significant. then I do a recieve of serial data. I hope this bit of information will be helpful
You will have to use bit-banging for ISSP programming. Using serial port will not work, since it has extra bits. I request you to kindly refer to AN44168 PSoC® 1 Device Programming using External Microcontroller (HSSP) and PSoC® 1 ISSP Programming Specifications - CY8C21x12, CY8C21x23, CY8C21x34, CY8C23x33, CY8C24x23A, CY8C27x43, CY8CTMG110, CY8CTST110 for further information.
