Fix PADS_PCFG0.TWI0VSEL enums

The TWI0 Voltage Select field (PADS_PCFG0.TWI0VSEL) is incorrect.

The correct enumeration is:

0 – VDD_EXT = 3.3V, VBUS_TWI = 3.3V

1 – VDD_EXT = 1.8V, VBUS_TWI = 1.8V

2 – Reserved

3 – VDD_EXT = 1.8V, VBUS_TWI = 3.3V

4 – VDD_EXT = 3.3V, VBUS_TWI = 5.0V

5-7 – Reserved

Fix BUFRDERR bit description

Table 26-15 shows an incorrect BUFRDERR (Buffer Read Error) bit description.

INCORRECT: The TWI_MSTRSTAT.BUFRDERR indicates whether the current master transfer was aborted due to the detection of a NAK during data transmission. This bit is W1C.

0 No Status

1 Buffer Read Error

CORRECT: The TWI_MSTRSTAT.BUFRDERR indicates whether the current master transfer was aborted due to a buffer read error.

0 The current master transmit has not detected a buffer read error

1 The current master transfer was aborted due to a transmit buffer read error. At the time data was required by the transmit shift register the buffer was empty. This bit is cleared by writing a one to its bit location.
