PSoC 4000 Family: PSoC 4 Architecture TRM, Document No. 001-89309 Rev. *D 157
Nonvolatile Memory Programming
Return
19.5.11 Resume Non-Blocking
This function completes the additional phases of erase and program that were started using the non-blocking write row and
non-blocking program row system calls. This function must be called thrice following a call to Non-Blocking Write Row or once
following a call to Non-Blocking Program Row from the SPC ISR. No other system calls can execute until all phases of the
program or erase operation are complete. More details on the procedure of using the non-blocking functions are explained in
Blocking and Non-Blocking System Calls on page 148.
