Register Descriptions
Table 14-9 describes RSMP fields.
14.3.9 Transmit Space Available Register (TSPC)
The transmit space available register (TSPC), Figure 14-10, shows available bytes in Tx
FIFO. TSPC supports UART1 only and can be used in UART and modem modes.
Table 14-10 describes TSPC fields.
14.3.10 UART Command Registers (UCRn)
The UART command registers (UCRn), Figure 14-11, supply commands to the UART in
both UART and modem modes. Only multiple commands that do not conflict can be
specified in a single write to a UCRn. For example,
RESET TRANSMITTER and ENABLE
TRANSMITTER
cannot be specified in one command.
