The operations of these instructions, as well as their effects on flag and status bits, are exactly the same.
Each state time lasts for two oscillator periods. Thus a machine cycle takes 12 oscillator periods or 1us if the oscillator fre- quency In general, most register bits go to their reset value irrespective of the reset condition, but there are a few flags whose state Each of the interrupt sources has an individual priority bit, flag, interrupt vector and enable bit.
In addition, the interrupts can be globally enabled or In the same machine cycle, the sampled inter- rupts are polled and their priority is resolved.
If certain conditions are met then the Each interrupt source can be individually programmed to one of 2 priority levels by setting or clearing bits in the IP registers. An interrupt service routine in progress can be interrupted by a higher priority interrupt, but not by another If the polling cycle is not the last machine cycle of the instruc- tion being executed, then an additional delay is introduced.
The maximum response time if no other interrupt is in service occurs if A machine cycle equals oscillator periods, and it depends on 12T mode or 6T mode that the user configured this device.
The selection of the time-base in the timer mode is similar to that in Mode 0. The gate function operates similarly to that in Mode 0. Figure 4 Bit Capture Mode The serial port is capable of synchronous as well as asynchronous communication. In Synchronous mode the device generates the clock and operates in a half duplex mode.
The 16 states of the counter effectively divide the bit time into 16 slices. The bit detection is done on a best of three basis. The bit detector samples the RxD pin, at the 8th, 9th and 10th counter states. Transmission begins with a write to SBUF. The serial data is brought out on to TxD pin at S6P2 following the Otherwise the received frame may be lost. After the middle of the stop bit, the receiver goes Note: Timer 0 for program, erase, read on ISP mode. ISP operation voltage 3.
NO Setting Timer and enable Timer interrupt for wake-up. It may be set after the programmer finishes the programming and verifies sequence. Once these bits are Typical values are not guaranteed. The values listed are tested at room temperature and based on a limited number of samples. There are no duty cycle requirements on the XTAL1 input. Application Note: In-system Programming Software Examples This application note illustrates the in-system programmability of the microcontroller.
