Operation of Data Transfer of Output Data Register
Eight methods can be used to transfer data from the Output Data Buffer Register
(OPDBR) to the Output Data Register (OPDR) automatically, which are described in the
following paragraphs. Each method is selected by setting the OPS2 to OPS0 bits in the
Output Control Register (OPCR).
■
Operation of Data Transfer of Output Data Register
There are eight methods of data transfer from Output Data Buffer Registers (OPDBRB to OPDBR0) to the
Output Data Register (OPDR):
•
OPDBR0 Write
•
16-bit Reload Timer Underflow
•
Position Detection
•
Position Detection and 16-bit Reload Timer Underflow
•
Position Detection or 16-bit Reload Timer Underflow
•
One-shot Position Detection
•
One-shot Position Detection and 16-bit Reload Timer Underflow
•
One-shot Position Detection or 16-bit Reload Timer Underflow
The value of the Output Data Buffer Register (OPDBR) which is selected by the BNKF, RDA2 to RDA0
bits in Output Data Register (OPDR), is transferred to the Output Data Register (OPDR) when the write
signal is generated from the Data Write Control Circuit. However, at the time when OPS2 to OPS0 = 000
B
,
the value of OPDBR0 is always transferred to the Output Data Register (OPDR) in spite of the value of
BNKF, RDA2 to RDA0 bits. Figure 15.6-2 shows structure between OPDBRB to OPDBR0 registers and
OPDR register.
Note:
When the data transfer method is changed, the next Data Buffer Register to be selected is always
specified by the BNKF, RDA2 to RDA0 bits in the Data Output Register. This does not apply to the
OPDBR0 Write method, in OPDBR0 Write method BNKF, RDA2 to RDA0 bits are ignored. Word
access to Output Data Register must be used.
