Description
SPI 1 clock polarity
0 Negative clock polarity (SCK low when idle)
1 Positive clock polarity (SCK high when idle)
SPI 1 clock phase
0 Data centered on first edge of SCK period
1 Data centered on second edge of SCK period
Bit order for transfers
0 LSB first
1 MSB first
Baud rate exponent value. BAUD_E along with BAUD_M decides the UART 1
baud rate and the SPI 1 clock (SCK) frequency
U1DBUF (0xF9) – USART 1 Receive/Transmit Data Buffer
Bit Name
7:0 DATA[7:0]
Reset R/W
0x00 R/W
Description
USART 1 receive and transmit data buffer. Writing data to U1DBUF places
the data into the internal transmit buffer. Reading U1DBUF returns the
contents of the receive buffer.
U1BAUD (0xFA) – USART 1 Baud Rate Control
Bit Name
7:0 BAUD_M[7:0]
Reset R/W
0x00 R/W
Description
Baud rate mantissa value. BAUD_M along with BAUD_E decides the UART 1
baud rate and the SPI 1 clock (SCK) frequency
