Bits5–4:
GATE1: Timer 1 Gate Control.
0: Timer 1 enabled when TR1 = 1 irrespective of /INT1 logic level. /INT1 is activated when
the internal oscillator resumes from a suspended state.
1: Timer 1 enabled only when TR1 = 1 AND /INT1 is active. /INT1 is activated every 2 low
frequency oscillator clock cycles. This is a rate of 40kHz.
Reserved. Read = 0b. Must write 0b.
T1M1-T1M0: Timer 1 Mode Select.
These bits select the Timer 1 operation mode.
