D-A Converter
This is an 8-bit, R-2R type D-A converter. The microcomputer contains one independent D-A converter of this type.
D-A conversion is performed when a value is written to the corresponding D-A register. Bit 0 (D-A output
enable bit) of the D-A control register decide if the result of conversion is to be output. Do not set the target
port to output mode if D-A conversion is to be performed. When D-A output is set for enabled, the corre-
sponding port is inhibited to be pulled up.
Output analog voltage (V) is determined by a set value (n : decimal) in the D-A register.
V = VREF X n/ 256 (n = 0 to 255)
VREF: reference voltage
Table 1.17.1 lists the performance of the D-A converter. Figure 1.17.1 shows the block diagram of the D-A
converter, Figure 1.17.2 shows the D-A control register and Figure 1.17.3 shows D-A converter equivalent
circuit.
