(2) 16-bit timer capture/compare register 00 (CR00)

(1) 16-bit timer counter 00 (TM00)
TM00 is a 16-bit read-only register that counts count pulses.
The counter is incremented in synchronization with the rising edge of the input clock.
The count value is reset to 0000H in the following cases.
<1> At RESET input
<2> If TMC003 and TMC002 are cleared
<3> If the valid edge of the TI000 pin is input in the mode in which clear & start occurs upon input of the valid
<4> If TM00 and CR00 match in the mode in which clear & start occurs on a match of TM00 and CR00
<5> OSPT00 is set in one-shot pulse output mode
CR00 is a 16-bit register that has the functions of both a capture register and a compare register. Whether it is
used as a capture register or as a compare register is set by bit 0 (CRC000) of capture/compare control register
00 (CRC00).
CR00 can be set by a 16-bit memory manipulation instruction.
RESET input clears this register to 0000H.
When CR00 is used as a compare register
The value set in CR00 is constantly compared with 16-bit timer counter 00 (TM00) count value, and an
interrupt request (INTTM00) is generated if they match. The set value is held until CR00 is rewritten.
When CR00 is used as a capture register
It is possible to select the valid edge of the TI000 pin or the TI001 pin as the capture trigger. The TI000 or
TI001 pin valid edge is set using prescaler mode register 00 (PRM00) (see Table 7-2).
