The pattern memory holds up to 54 instructions with logical addresses from 0 to 53. Upon detection a rising edge of the LS_START signal, the pattern start address is reset to the START_ADDR in the register. If, however, START_ADDR is greater than 53, the pattern sequence terminates immediately, similar to executing an END instruction. If during normal operation the logical address should overflow, the address counter remains set to 53 and is not further incremented. Any instruction stored at address 53 may be executed multiple times until the next LS_START pulse is detected and the address counter is reset to the START_ADDR value. An exception to this rule is the JMP and EEQ instruction which terminate the sequence immediately if the target address is >53. See respective instruction description for detail.
