Preliminary Data Sheet
12. DSU (Deadman’s SW Unit)
12.1 General
The DSU automatically detects a hang-up of the V
R
4102 and resets the V
R
4102. By stopping a hang-up at the
earliest stage by using the DSU, the destruction of data can be minimized.
The DSU can set for a cycle of up to 15 seconds in units of 1 second. Set the DSWCLR bit of the DSUCLRREG
register to 1 within this time in software. If the bit is not set within the time, the CPU is reset (refer to
4. INITIALIZATION
INTERFACE
).
