2.8.3. SLD Service
SLD Service
set timeout_in_ms 1000 set lock_failed [sld_lock $sld_service_path $timeout_in_ms]
This code attempts to lock the selected SLD node. If it is already locked, sld_lock waits for the specified timeout. Confirm the procedure returns non-zero before proceeding. Set the instruction register and capture the previous one:
if {$lock_failed} { return } set instr 7 set delay_us 1000 set capture [sld_access_ir $sld_service_path $instr $delay_us]
The 1000 microsecond delay guarantees that the following SLD command executes least 1000 microseconds later. Data register access works the same way.
set data_bit_length 32 set delay_us 1000 set data_bytes [list 0xEF 0xBE 0xAD 0xDE] set capture [sld_access_dr $sld_service_path $data_bit_length $delay_us \ $data_bytes]
Shift count is specified in bits, but the data content is specified as a list of bytes. The capture return value is also a list of bytes. Always unlock the SLD node once finished with the SLD service.
