Operating Mode
(1) Real-time output buffer register 1 (RTBL01, RTBH01)
This register consists of two 4-bit Note registers that hold output data in advance.
The addresses of RTBL01 and RTBH01 are mapped individually in the special function register (SFR) area as
shown in Figure 10-2.
When specifying 4 bits
When specifying 6 bits
6-bit data to either RTBL01 or RTBH01. The data of both RTBL01 and RTBH01 can be read all at once
regardless of which address is specified.
Figure 10-2 shows the configuration of RTBL01 and RTBH01, and Table 10-2 shows operations during
manipulation of RTBL01 and RTBH01.
Note For RTBH01, only 2 of the 4 bits are valid.
Output data should be set in RTBL01 and RTBH01 by the time a real-time output trigger is generated.
