184 / 437 page  Embedded Controller Modules (Continued) www.national.com 184 Revision 1.07 Voltage Channel 1 Data Buffer (VCHN1DAT) This register (buffer) holds the data measured by Voltage Channel 1. Location: 00 FF3616 Type: RO Voltage Channel 2 Control Register (VCHN2CTL) This register controls the operation and indicates the status of Voltage Channel 2. VCHN2CTL is set to 1F16 on reset. Location: 00 FF3816 Type: Varies per bit Voltage Channel 2 Data Buffer (VCHN2DAT) This register (buffer) holds the data measured by the Voltage Channel 2. Location: 00 FF3A16 Type: RO Bit 15 14 13 12 11 10 9876543210 Name Reserved VCHDAT Bit Description 9-0 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 173. 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. Range: 0 to 1023 (0 to VFS); 10-bit, unsigned value with 1 LSB = VFS/1024 (the value at reset is undefined). 15-10 Reserved. Bit 76543210 Name DATVAL CSCALE INTDVEN SELIN Reset 00011111 Bit Type Description 4-0 R/W SELIN (Selected Input). Same as Voltage Channel 1. 5 R/W INTDVEN (Interrupt from Data Valid Enable). Same as Voltage Channel 1. 6 R/W CSCALE (Channel Scale). Same as Voltage Channel 1. 7 R/W1C DATVAL (Data Valid). Same as Voltage Channel 1. Bit 15 14 13 12 11 10 9876543210 Name Reserved VCHDAT Bit Description 9-0 VCHDAT (Voltage Channel 2 Data). Same as Voltage Channel 1. 15-10 Reserved. |
