Protect
Figure 2.1.2. Set-up procedure for protect function
2.1.3 Precaution for Protect
(1) The write-enable bit of port 9 direction register and SI/Oi control register (i=3,4) goes to “0”
when the next write instruction is executed after write-enabled state is readied. Make
changes in input/output and SI/Oi control register (i=3,4) immediately after the instruction that
sets “1” in the write-enable bit of port P9 direction register and SI/Oi control register
(i=3,4)(avoid causing an interrupt). Also take measures to prevent DMA transfer from being
executed.
