D-A Converter
Table 1.18.1. Performance of D-A converter
Figure 1.18.1. Block diagram of 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. When the D-A output is enabled, the pull-
up function of the corresponding port is automatically disabled.
Output analog voltage (V) is determined by a set value (n : decimal) in the D-A register.
Table 1.18.1 lists the performance of the D-A converter. Figure 1.18.1 shows the block diagram of the D-A
converter. Figure 1.18.2 shows the D-A control register. Figure 1.18.3 shows the D-A converter equivalent
circuit.
