Table 117. Peripheral Configuration SFR (PERIPH, 0xF4)

Bit

Mnemonic

Default

Description

RXFLAG

If set, indicates that a Rx edge event triggered wake-up from PSM2.

VSWSOURCE

Indicates the power supply that is connected internally to VSWOUT. If set, VSWOUT = VDD. If

cleared, VSWOUT = VBAT.

VDD_OK

If set, indicates that VDD power supply is ok for operation.

PLL_FLT

If set, indicates that PLL is not locked.

REF_BAT_EN

If set, the internal voltage reference is enabled in PSM2 mode. This bit should be set if the

LCD is on in PSM2 mode.

Reserved

This bit should be kept to zero.

Controls the function of the P1.0/RxD pin.

RXPROG [1:0]

Result

GPIO

Rx with wake-up disabled

1 to 0

RXPROG[1:0]

Table 118. Start ADC Measurement SFR (ADCGO, 0xD8)

Bit

Address

Mnemonic

Default

Description

0xDF

PLL_FTL_ACK

Set this bit to clear the PLL fault bit, PLL_FLT in the PERIPH register. A PLL fault

is generated if a reset was caused because the PLL lost lock.

6 to 3

0xDE to 0xDB

Reserved

Reserved.

0xDA

VDCIN_ADC_GO

Set this bit to initiate an external voltage measurement. This bit is cleared

when the measurement request is received by the ADC.

0xD9

TEMP_ADC_GO

Set this bit to initiate a temperature measurement. This bit is cleared when

the measurement request is received by the ADC.

0xD8

BATT_ADC_GO

Set this bit to initiate a battery measurement. This bit is cleared when the

measurement request is received by the ADC.
