SN8F2280 Series
USB 2.0 Full-Speed 8-Bit Micro-Controller
1 = External clock from P0.1/INT1 pin.

Bit 1
Bit 0
ALOAD1: Auto-reload control bit. Only valid when PWM1OUT = 0.
0 = Disable TC1 auto-reload function.
1 = Enable TC1 auto-reload function.
TC1OUT: TC1 time out toggle signal output control bit. Only valid when PWM1OUT = 0.
0 = Disable, P5.4 is I/O function.
1 = Enable, P5.4 is output TC0OUT signal.
PWM1OUT: PWM output control bit.
0 = Disable PWM output.
1 = Enable PWM output. PWM duty controlled by TC1OUT, ALOAD1 bits.
Note: When TC1CKS=1, TC0 became an external event counter and TC1RATE is useless. No more P0.1
interrupt request will be raised. (P0.1IRQ will be always 0).
