Processor Mode
Software wait
Table 1.7.1. Software waits and bus cycles
A software wait can be inserted by setting the wait bit (bit 7) of the processor mode register 1 (address
0005
A software wait is inserted in the internal ROM/RAM area by setting the wait bit of processor mode register
1. When set to "0", each bus cycle is executed in one BCLK cycle. When set to "1", each bus cycle is
executed in two BCLK cycles. After the microcomputer has been reset, this bit defaults to "0". When set to
"1", a wait is applied to all memory areas (two BCLK cycles). Set this bit after referring to the recommended
operating conditions (main clock input oscilliation frequecny) of the electrical characteristics.
The SFR area is always accessed in two BCLK cycles regardless of the setting of these control bits.
Table 1.7.1 shows the software wait and bus cycles.
Note: Before attempting to change the contents of the processor mode register 1, set bit 1 of the protect
