Voltage Channel 2 Control Register (VCHN2CTL)
This register controls the operation and indicates the status of Voltage Channel 2. VCHN2CTL is set to 1F
Location: 00 FF38
Type:
Voltage Channel 2 Data Buffer (VCHN2DAT)
This register (buffer) holds the data measured by the Voltage Channel 2.

VCHDAT (Voltage Channel 1 Data). Selected input voltage data, measured by Voltage Channel 1. To calculate
the voltage, see Section 4.11.3 on page 167. VCHN1DAT holds valid result when DATVAL bit in VCHN1CTL
register is set. To prepare for consecutive result, clear DAVAL after reading the data from VCHDAT.
