Description
b0
WKUS0
Wakeup source: EXT1(IOA0); 0: disabled, 1: enabled
Falling (default)/Rising edge from IOA0 (set by Port_IO_Config($0010), b6)
b1
WKUS1
Wakeup source: EXT2(IOA1); 0: disabled, 1: enabled
Falling (default)/Rising edge from IOA1 (set by Port_IO_Config($0010), b7)
b2
WKUS2
Wakeup source: 2Hz or 1Hz (set by P_0DH_Timer_INT2($000D), b3 )
0: disabled, 1: enabled
b3
WKUS3
Wakeup source: HSCK/N_INT (37.9KHz divided by 2/4/8/16, set by
P_0CH_Timer_INT1 ($000C), b[4:3])
0: disabled, 1: enabled
b4
WKUS4
Wakeup source: LSCK/M_INT (4096/1024/128/64/32/16/8/4 Hz, set by
P_0DH_Timer_INT2($000D), b[6:4] ) ; 0: disabled, 1: enabled
b5
WKUS5
Wakeup source: Timer Overflow IRQ
0: disabled, 1: enabled
b6
WKUS6
Wakeup source: key change (INB[7:0])
0: disabled, 1: enabled
b7
WKUS7
0: Timer overflow NMI disabled (timer overflow as IRQ)
1: Timer overflow NMI enabled (WKUS5 will be auto-disabled)
Read for checking NMI occurrence.
Note:
1. When WKUC5 clears TMO (timer overflow), it will also clear WKU7 (NMI).
2. The WKUS7 configures TMO as IRQ (WKUS7=0) or NMI (WKUS7=1). If WKUS7 is configured TMO as
NMI (WKUS7=1), WKUC5 (TMO IRQ) will be disabled automatically.
