(d) Prescaler mode register 0n (PRM0n)
(e) 16-bit timer counter 0n (TM0n)
(f) 16-bit capture/compare register 00n (CR00n)
(g) 16-bit capture/compare register 01n (CR01n)
Remark n = 0:
ES1n1
0/1
By reading TM0n, the count value can be read.
When this register is used as a compare register and when its value matches the count value of TM0n, an
interrupt signal (INTTM00n) is generated. The count value of TM0n is not cleared.
To use this register as a capture register, select either the TI00n or TI01n pin input as a capture trigger.
When the valid edge of the capture trigger is detected, the count value of TM0n is stored in CR00n.
When this register is used as a compare register and when its value matches the count value of TM0n, an
interrupt signal (INTTM01n) is generated. The count value of TM0n is not cleared.
When this register is used as a capture register, the TI00n pin input is used as a capture trigger. When the
valid edge of the capture trigger is detected, the count value of TM0n is stored in CR01n.
