; wait for the page program to end. Whether or not the program has ended can be checked by two
; methods: 1) write a read status command to read the status from the NDD7 to NDD0 pins (polling)
; method), and 2) use a Ready interrupt by detection of NDRB pin rising edge. The following describes a
; case in which the second method is used.
;
NDFINTC
Have the INTC enable an NDFC interrupt. (Details are omitted.)
