DAC Load Control (LOADCON)
DACSEL = 06h 7 6 5 4 3 2 1 0 Reset Value
SFR B5h D3LOAD1 D3LOAD0 D2LOAD1 D2LOAD0 D1LOAD1 D1LOAD0 D0LOAD1 D0LOAD0 00h
D3LOAD1−0 (Available only on MSC1211 and MSC1212)
bit 7−6 The DAC load options are listed below:
DxLOAD OUTPUT MODE for
00 Direct load: write to DACxL directly loads the DAC buffer and the DAC output (write to DACxH does not load DAC output).
01 Delay load: the values last written to DACxL/DACxH will be transferred to the DAC output on the next MSEC timer tick.
10 Delay load: the values last written to DACxL/DACxH will be transferred to the DAC output on the next HMSEC timer tick.
11 Sync load: the values contained in the DACxL/DACxH registers will be transferred to the DAC output immediately after
11b is written to this register.

SFR B8h 1 PS1 PT2 PS0 PT1 PX1 PT0 PX0 80h
PS1 Serial Port 1 Interrupt. This bit controls the priority of the serial Port 1 interrupt.
bit 6 0 = Serial Port 1 priority is determined by the natural priority order.
1 = Serial Port 1 is a high-priority interrupt.
PT2 Timer 2 Interrupt. This bit controls the priority of the Timer 2 interrupt.
bit 5 0 = Timer 2 priority is determined by the natural priority order.
1 = Timer 2 priority is a high-priority interrupt.
PS0 Serial Port 0 Interrupt. This bit controls the priority of the serial Port 0 interrupt.
bit 4 0 = Serial Port 0 priority is determined by the natural priority order.
1 = Serial Port 0 is a high-priority interrupt.
PT1 Timer 1 Interrupt. This bit controls the priority of the Timer 1 interrupt.
bit 3 0 = Timer 1 priority is determined by the natural priority order.
1 = Timer 1 priority is a high-priority interrupt.
PX1 External Interrupt 1. This bit controls the priority of external interrupt 1.
bit 2 0 = External interrupt 1 priority is determined by the natural priority order.
1 = External interrupt 1 is a high-priority interrupt.
PT0 Timer 0 Interrupt. This bit controls the priority of the Timer 0 interrupt.
bit 1 0 = Timer 0 priority is determined by the natural priority order.
1 = Timer 0 priority is a high-priority interrupt.
PX0 External Interrupt 0. This bit controls the priority of external interrupt 0.
bit 0 0 = External interrupt 0 priority is determined by the natural priority order.
1 = External interrupt 0 is a high-priority interrupt.
