8.0
Before a device can be programmed, the programmer
must check the status of the device to ensure that it is
ready to receive information.

CHECK DEVICE STATUS
statusVal = XferData (MCHP_STATUS)
No
SendCommand (MTAP_COMMAND)
SendCommand (MTAP_SW_MTAP)
SetMode (6’b011111)
Set MCLR low

Yes
4-Wire
8.1
Four-wire JTAG programming is a Mission mode
operation and therefore the setup sequence to begin
programing should be done while asserting MCLR.
Holding the device in Reset prevents the processor
from executing instructions or driving ports.
The following steps are required to check the device
status using the 4-wire interface:
1.
2.
3.
4.
5.
6.
8.2
The following steps are required to check the device
status using the 2-wire interface:
1.
2.
3.
4.
5.
Note:
Set MCLR pin low.
SetMode (6’b011111) to force the Chip TAP
controller into Run Test/Idle state.
SendCommand (MTAP_SW_MTAP).
SendCommand (MTAP_COMMAND).
statusVal = XferData (MCHP_STATUS).
If CFGRDY (statusVal<3>) is not ‘1’ and
FCBUSY (statusVal<2>) is not ‘0’ GOTO step 5.

2-Wire Interface
If CFGRDY and FCBUSY do not come to
the proper state within 10 ms, the
sequence may have been executed wrong
or the device is damaged.
