Function
1/4 system clock is used (φ = 24MHz, 25.16 MHz)
1/3 system clock is used (φ = 18MHz, 18.87 MHz)
1/2 system clock is used (φ = 12MHz, 12.58 MHz)
Setting prohibited
Description
Last Byte Underrun Enable
Sets whether to generate an underrun error when the last
data field byte is transferred in data transmission.
If the IEB reads from IETBR when the TxRDY flag is set
(the transmit buffer register (IETBR) is empty), an underrun
error occurs. In transmission using the DTC, an underrun
error occurs at the last byte transmission if the CPU did not
clear the TxRDY flag, because the DTC does not clear the
TxRDY flag. When the DTC is used, set this bit to 0 to
mask an underrun error generated at the last byte
transmission. When the DTC is not used, set this bit to 1 to
generate an underrun error at the last byte transmission.
0: An underrun error does not occur at the last byte
1: An underrun error does not occur at the last byte
Input Clock Select
Selects clock used by the IEB. See table 17.7.
Reserved
This bit is always read as 0 and cannot be modified.
