(1) 16-bit timer counter 00 (TM00)

Cautions 1. The valid edge of TI010 and timer output (TO00) cannot be used for the P01 pin at the same time.
TM00 is a 16-bit read-only register that counts count pulses.
The counter is incremented in synchronization with the rising edge of the count clock.
The count value of TM00 can be read by reading TM00 when the value of bits 3 and 2 (TMC003 and TMC002) of 16-
bit timer mode control register 00 (TMC00) is other than 00. The value of TM00 is 0000H if it is read when TMC003
and TMC002 = 00.
The count value is reset to 0000H in the following cases.
• At reset signal generation
• If TMC003 and TMC002 are cleared to 00
• If the valid edge of the TI000 pin is input in the mode in which the clear & start occurs when inputting the valid edge
• If TM00 and CR000 match in the mode in which the clear & start occurs when TM00 and CR000 match
• OSPT00 is set to 1 in one-shot pulse output mode or the valid edge is input to the TI000 pin

A value that has been once captured remains stored in CR000 unless the device is reset. If the
mode has been changed to the comparison mode, be sure to set a comparison value.
