(ii) Wait Operation
The wait operation occurs if /STWT bit of ICONT register is
0
, status byte transmission is performed and RAM
data transmission is operational. Then, when the data writing of micom into STATUS register is finished, /STUOP
bit of ISTATE register gets to
0
, but /STOPR bit will be
0
and /SREN pin will be
L
, even after RAM data
transmission is finished. The rest of this operation is the same as normal operation.
