Sep 30, 2010
Reset, NMI, INTWDT2, WAIT, and HLDRQ signals can be masked.
The maskable functions with the debugger (ID850QB) and the corresponding V850ES/JG3 functions are listed below.
(1) On-chip debug mode register (OCDM)
The OCDM register is used to select the normal operation mode or on-chip debug mode. This register is a special
register and can be written only in a combination of specific sequences (see 3.4.7 Special registers).
This register is also used to specify whether a pin provided with an on-chip debug function is used as an on-chip
debug pin or as an ordinary port/peripheral function pin. It also is used to disconnect the internal pull-down resistor
of the P05/INTP2/DRST pin.
The OCDM register can be written only while a low level is input to the DRST pin.
This register can be read or written in 8-bit or 1-bit units.
