(2) Timer data register 0n (TDR0n)
Address: FFF18H, FFF19H (TDR00), FFF1AH, FFF1BH (TDR01),
(n = 0 to 7)
TDR0n
This is a 16-bit register from which a capture function and a compare function can be selected.
The capture or compare function can be switched by selecting an operation mode by using the MD0n3 to
MD0n0 bits of TMR0n.
The value of TDR0n can be changed at any time.
This register can be read or written in 16-bit units.
Reset signal generation clears this register to 0000H.
(i) When TDR0n is used as compare register
(ii) When TDR0n is used as capture register
Counting down is started from the value set to TDR0n. When the count value reaches 0000H, an interrupt
signal (INTTM0n) is generated. TDR0n holds its value until it is rewritten.
Caution TDR0n does not perform a capture operation even if a capture trigger is input, when it is
The count value of TCR0n is captured to TDR0n when the capture trigger is input.
A valid edge of the TI0k pin can be selected as the capture trigger. This selection is made by TMR0n.
