Note on Protect Register:
Note on Memory Access:
Notes on A/D Conversion:
The protect is not canceled when bit 2 of protect register PRCR (PRC2), which enables writing into the port P9
direction register and the SI/Oi control register, is changed with the below procedure.
When setting memory expansion mode as a processor mode, it may be changed to memory expansion mode
temporarily before the user program itself changes from single-chip mode to memory expansion mode.
Take due consideration on this phenomenon in the following cases:
When setting the register below to use the analog input port selection function, you need to set the direction
register of port P15 for a pin that performs A/D conversion to “input”.
When setting the register below to use multi-port sweep mode, you need to set the direction register of port P15
for an pin that performs A/D conversion to “input”. And you need to set the function selection register of port
P15 for a pin that performs A/D conversion to "I/O port".
Because a converter board and other devices are used between the evaluation MCU and the user system, the
A/D converter operates differently from an actual MCU. Make the final evaluation of the A/D converter using
an actual MCU.
(1) Step execution of an instruction setting PRC2 to "1"
(2) Setting a break point from an instruction setting PRC2 to "1" to where the port P9 direction register or the
(3) Setting (“1”) PRC2 from the dump window or script window during use program execution
And you need to set the function selection register of port P15 for a pin that performs A/D conversion to “I/O
port)”
A/D0 control register 2 (address 394h)
A/D0 control register 4 (address 392h)
(1) Immediately before executing the program after setting a software break
(2) Immediately after stopping the program when a software break is set
Also, when the P0 group and P2 group are selected for A/D input, port P15 cannot be used as an I/O port, When
setting the register above, port P15 cannot be used as an I/O port even if A/D conversion is halting
For the switch SW5, refer to “2.9.1 Setting Switches of Emulator” (page 39).
Also, when the P0 group and P2 group are used for multi-port sweep mode, port P15 cannot be use as an I/O
port. When setting the register above, port P15 cannot be used as an I/O port even if a/D conversion is halting.
