UART1, UART2
The UART consists of two channels: UART1 and UART2. Each
has a dedicated timer provided to generate transfer clocks and op-
erates independently. Both UART1 and UART2 have the same
functions.
Twelve serial data transfer formats can be selected, and the trans-
fer formats used by a transmitter and receiver must be identical.
The transmit and receive shift registers each have a buffer, but the
two buffers have the same address in a memory. Since the shift
register cannot be written to or read from directly, transmit data is
written to the transmit buffer register, and receive data is read
from the receive buffer register.
The transmit buffer register can also hold the next data to be
transmitted, and the receive buffer register can hold a character
while the next character is being received.
The transfer speed (baud rate) is expression as follows:
Transfer speed (baud rate) = fi / {(n + 1) 16 }
n: The contents of UARTx (x = 1, 2) baud rate generator
fi: Using UART clock prescaling select bits, select any one of
φ, φ/

φ/32, φ/256, SCSGCLK, SCSGCLK/8, SCSGCLK/32 and
