Request Identifying the CC2541F256_Chip_Set problem.
Within the interrupt occurs in PORT1[2], the ISR routine P1IFG_2=1, and P1IFG_3=1 Register is set at the same time is a problem occurred.
PORT-1 [0:3] are configured as shown in the figure.
As follows: .
STEP1: the SW0 or SW1 Press -> P1IFG_0 = 1 or P1IFG_1 = 1, Error No (Set = 1).
STEP2 : SW3 Press -> P1IFG_3 = 1, No Error( Set = 1 ).
STEP3 : SW2 Press -> P1IFG_2 = 1 and P1IFG_3 = 1, Error simultaneous SET (Set = 1).
STEP4: STEP2 + STEP3 repeat, occurring irregularly.
The problem as described above was confirmed SmartRF05EB(Rev1.8.1.2) Board 2 SET, and My Target Board 5 SET.
all The same phenomenon occurs.
