R/W
Interrupt enable bits. These bits enable the XFER_BUSY, the RTC_1SEC, etc. The
bits are set by hardware and cannot be set by writing a 1. The bits are reset by writing
0. Note that if one of these interrupts is to enabled, its corresponding 8051 EX enable
bit must also be set. See 2.4.9 Interrupts, for details.
EW_DIO4
28B3[2]
0
R/W
Connects SEGDIO4 to the WAKE logic and permits SEGDIO4 rising to wake the part.
This bit has no effect unless DIO4 is configured as a digital input.
EW_DIO52
28B3[1]
0
R/W
Connects SEGDIO52 to the WAKE logic and permits SEGDIO52 rising to wake the part.
This bit has no effect unless SEGDIO52 is configured as a digital input.
EW_DIO55
28B3[0]
0
R/W
Connects SEGDIO55 to the WAKE logic and permits the SEGDIO55 rising edge to
awaken the part. This bit has no effect unless SEGDIO55 is configured as a digital
input.
EW_PB
28B3[3]
0
R/W
Connects PB to the WAKE logic and permits the PB rising edge to awaken the part. PB
is always configured as an input.
EW_RX
28B3[4]
0
R/W
Connects RX to the WAKE logic and permits the RX rising edge to awaken the part.
See the WAKE description in 3.4 Wake on Timer for de-bounce issues.
FIR_LEN[1:0]

The ADC LSB size and full-scale values depend on the FIR_LEN[1:0] setting. Refer to
Table 83 on page 126 and Table 105 on page 144 for details.
