Note 1: When selecting programmable one-shot generation mode, output is set for Port P31 regardless of the value of the
direction register.
Note 2: When this bit is cleared to "0", the timer reloads the content of the reload register before it stops. Read out the
count value before you stop the timer.

bit (Note 3)
Note 1: When setting this bit to "1", the Prescaler Z Register must be set to "0016".
Note 2: When changing this bit to "1", set the INT0 input filter select bit (bit 0 at address 009616), the INT0 input polarity select bit (
bit 1 at address 009616), the INT0 input filter select bit (bits 0 and 1 at address 001E16) and the INT0 pin one-shot trigger
polarity select bit.
Note 3: This bit is valid only when the INT0 input polarity select bit (bit 1 at address 009616) is "0" (one-edge).
