Fig. 24 Bit configuration of processor mode register 0
Notes 1: While VSS level voltage is applied to pin MD0, this bit’s state is cleared to “0” at reset. While VCC level voltage is applied
to pin MD0, on the other hand, this bit’s state is set to “1” at reset. (Fixed to “1”.)
2: These bits are valid to the external area except for chip select area (area CSi). The bus cycle of area CSi is selected
by the corresponding area CSi bus cycle select bits 0, 1.
3: While VSS level voltage is applied to pin MD0, this bit’s state is cleared to “0” at reset. While VCC level voltage is applied
to pin MD0, on the other hand, this bit’s state is set to “1” at reset.

Processor mode register 0
Processor mode bits (Note 1)
0 0 : Single-chip mode
0 1 : Memory expansion mode
1 0 : Microprocessor mode
1 1 : Do not select.
Interrupt priority detection time select bits
0 0 : 7 cycles of fsys
0 1 : 4 cycles of fsys
1 0 : 2 cycles of fsys
1 1 : Do not select.
Software reset bit
By a write of “1” to this bit, the microcomputer will be reset, and then, restarted.
External bus cycle select bit 0 (Note 2)
See Figure 18.
Clock
φ1 output select bit (Note 3)
0 :
φ1 output is disabled. (P41 functions as an programmable I/O port pin.)
1 :
φ1 output is enabled. (P41 functions as the clock φ1 output pin.)
Address
