* The <<m_bit>> is reset to {cheri_int_mode_name} ({INT_MODE_VALUE}).
* The debugger can set the <<m_bit>> to {cheri_cap_mode_name} ({CAP_MODE_VALUE}) by executing <<MODESW_CAP>> from the program buffer.
** Executing <<MODESW_CAP>> causes the next instruction from the program buffer to be executed in {cheri_cap_mode_name}, and also sets the CHERI execution mode to {cheri_cap_mode_name} on future entry into debug mode.
** Executing <<MODESW_CAP>> causes subsequent instruction execution from the program buffer, starting from the next instruction, to be executed in {cheri_cap_mode_name}. It also sets the CHERI execution mode to {cheri_cap_mode_name} on future entry into debug mode.
** Therefore to enable use of a CHERI debugger, a single <<MODESW_CAP>> only needs to be executed once from the program buffer after resetting the core.
** The debugger can also execute <<MODESW_INT>> to change the mode back to {cheri_int_mode_name}, which also affects the execution of the next instruction in the program buffer, updates the <<m_bit>> of <<dinfc>> and controls which CHERI execution mode to enter on the next entry into debug mode.
