Read and write operations
Read and write operations of T00DR and T01DR are performed in the following manner during 16-bit
operation and PWM timer function (variable-cycle).
• Read from T01DR:
• Read from T00DR:
• Write to T01DR:

The following diagram illustrates how T00DR and T01DR registers read from and written to during 16-bit
operation.

Read access from the register also involves storing the T00DR value into the
internal read buffer.

Write access to the register also involves storing the value of the internal write
buffer into T01DR.
