4 / 31 page LC87F0G08A No.A2304-4/31 Interrupts 15 sources, 10 vectors 1) Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any interrupt requests of the level equal to or lower than the current interrupt are not accepted. 2) When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the highest level takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest vector address is given priority. No. Vector Address Level Interrupt Source 1 00003H X or L INT0 2 0000BH X or L INT1 3 00013H H or L INT2/T0L/INT4 4 0001BH H or L INT3/BT 5 00023H H or L T0H 6 0002BH H or L T1L/T1H 7 00033H H or L HPWM2 8 0003BH H or L SIO1 9 00043H H or L ADC 10 0004BH H or L P0/VCPWM Priority levels X > H > L Of interrupts of the same level, the one with the smallest vector address takes precedence. Subroutine Stack Levels: Up to 128levels (the stack is allocated in RAM.) High-speed Multiplication/Division Instructions 16 bits 8 bits (5 tCYC execution time) 24 bits 16 bits (12 tCYC execution time) 16 bits 8 bits (8 tCYC execution time) 24 bits 16 bits (12 tCYC execution time) Oscillation Circuits Internal oscillation circuits 1) Low-speed RC oscillation circuit: For system clock (approx.30kHz) 2) Medium-speed RC oscillation circuit: For system clock (1MHz) 3) Hi-speed RC oscillation circuit1: For system clock (8MHz) 4) Hi-speed RC oscillation circuit2: For High speed PWM (40MHz) System Clock Divider Function Can run on low consumption current. Minimum instruction cycle selectable from 375ns, 750ns, 1.5s, 3.0s, 6.0s, 12.0s, 24.0s, 48.0s, and 96.0 s (at 8MHz main clock) Internal Reset Circuit Power-on reset (POR) function 1) POR reset is generated only at power-on time. 2) The POR release level is 1.67V. Low-voltage detection reset (LVD) function 1) LVD and POR functions are combined to generate resets when power is turned on and when power voltage falls below a certain level. 2) The use/disuse of the LVD function and the low voltage threshold level can be selected from 7 levels (1.91V, 2.01V, 2.31V, 2.51V, 2.81V, 3.79V and 4.28V), through option configuration. |
