Bit 0—Multiprocessor Bit Transfer (MPBT): When transmission is performed using multiprocessor format in
asynchronous mode, MPBT stores the multiprocessor bit to be added to the transmit data.
The MPBT bit setting is invalid when multiprocessor format is not used, when not transmitting, and in clocked
synchronous mode.
14.2.8
BRR is an 8-bit register that sets the serial transfer bit rate in accordance with the baud rate generator operating clock
selected by bits CKS1 and CKS0 in SMR.
BRR can be read or written to by the CPU at all times.
BRR is initialized to H'FF by a reset, and by putting the device in standby mode or module stop mode. In the H8S/2398,
H8S/2394, H8S/2392, and H8S/2390, however, the value in BRR is initialized to H'FF by a reset, or in hardware standby
mode, but BRR retains its current state when the device enters software standby mode or module stop mode.
As baud rate generator control is performed independently for each channel, different values can be set for each channel.
Table 14-3 shows sample BRR settings in asynchronous mode, and table 14-4 shows sample BRR settings in clocked
synchronous mode.
