(1) Setting Processor Modes
Processor mode is available only: single-chip mode.
Processor mode is set by using the CNVSS pin and the PM01 to PM00 bits in the PM0 register.
Table 1.6.1 shows the processor mode after hardware reset. Table 1.6.2 shows the PM01 to PM00 bits
set values and processor modes. For setting Single-chip mode. CNVss should be kept Vss level. And
PM01 to PM00 of PM0 register should be set "00."
