0 : Edge trigger at falling edge

1 : Edge trigger at rising edge

0 : Outputs "H" level one-shot pulse.

Outputs "L" when the timer is stopped.

1 : Outputs "L" level one-shot pulse

Outputs "H" when the timer is stopped.

0 : INT0 pin one-shot trigger disabled

1 : INT0 pin one-shot trigger enabled(2)

NOTES:

1. The INOSEG bit is valid only when the INT0PL bit in the INTEN register is set to "0" (one-edge).

2. The INOSGT bit must be set to “1” after the INT0EN bit the INOSEG register and the INOSEG bit in the PUM register are set.

When setting the INOSTG bit to "1" (INT0 pin one-shot trigger enabled), the INT0F0 and INT0F1 bits in the INT0F register

must be set.

The INOSTG bit must be set to “0” (INT0 pin one-shot trigger disabled) after the TZS bit in the TYZMR register is set to “0”

(count stop).
