EXITING PROGRAMMING
MODE
Once a device has been properly programmed, the
device must be taken out of Programming mode to start
proper execution of its new program memory contents.
15.1
4-wire Interface
Exiting Test mode is done by removing VIH from MCLR,
as illustrated in Figure 15-1. The only requirement for
exit is that an interval, P16, should elapse between the
last clock and program signals before removing VIH.
FIGURE 15-1:
4-WIRE EXIT TEST MODE
The following steps are required to exit Test mode:
1.
SetMode (5’b11111).
2.
Assert MCLR.
3.
Remove power (if the device is powered).
15.2
2-wire Interface
Exiting Test mode is done by removing VIH from MCLR,
as illustrated in Figure 15-2. The only requirement for
exit is that an interval, P16, should elapse between the
last clock and program signals on PGECx and PGEDx
before removing VIH.
FIGURE 15-2:
2-WIRE EXIT TEST MODE
The following list provides the actual steps required to
exit test mode:
1.
SetMode (5’b11111).
2.
Assert MCLR.
3.
Issue a clock pulse on PGECx.
4.
Remove power (if the device is powered).
