10.7.6 CPU reset Commands
c17 rst
(reset) [ICD Mini / SIM]
Operation
Resets the CPU.
As a result, the CPU is reset to its initial state as shown below.
(1) Internal registers of the CPU
r0–r7: 0x000000
pc: Boot address (reset vector in the trap table)
sp: 0xfffffc
psr: 0x00 (IL = 000, IE = 0, CVZN = 0000)
(2) The execution counter is cleared to 0.
(3) The [Source] and [Registers] windows reappear.
Because the PC is set to the boot address, the [Source] window redisplays the program beginning with that
address. The [Registers] window reappears with the same settings as (1).
