D-A Converter
This is an 8-bit, R-2R type D-A converter. The microcomputer contains two independent D-A converters of
this type.
D-A conversion is performed when a value is written to the corresponding D-A register. Bits 0 and 1 (D-A
output enable bits) 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.
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 1.41 lists the performance of the D-A converter. Figure 1.80 shows a block diagram of the D-A
converter. Figure 1.81 shows the configuration of the D-A control register.
