• Manufacturer Part Number: HD6412350
• Description: (HD6412350 / HD6432351) 16-BIT MICROCONTROLLER
• Manufacturer: Hitachi

Bits 3 to 0—Operate in the same way as for the normal SCI. For details, see section 13.2.7, Serial
Status Register (SSR).
However, the setting conditions for the TEND bit, are as shown below.

Note: etu: Elementary Time Unit (time for transfer of 1 bit)
14.2.3
Note: * When the smart card interface is used, be sure to make the 0 or 1 setting shown for bits 6,
The function of bit 7 of SMR changes in smart card interface mode.
Bit 7—GSM Mode (GM): Sets the smart card interface function to GSM mode.
This bit is cleared to 0 when the normal smart card interface is used. In GSM mode, this bit is set
to 1, the timing of setting of the TEND flag that indicates transmission completion is advanced
and clock output control mode addition is performed. The contents of the clock output control
mode addition are specified by bits 1 and 0 of the serial control register (SCR).

When 0 is written to TDRE after reading TDRE = 1
When the DMAC or DTC is activated by a TXI interrupt and write data to TDR
Upon reset, and in standby mode or module stop mode
When the TE bit in SCR is 0 and the ERS bit is also 0
When TDRE = 1 and ERS = 0 (normal transmission) 2.5 etu after transmission of a
1-byte serial character when GM = 0
When TDRE = 1 and ERS = 0 (normal transmission) 1.0 etu after transmission of a
1-byte serial character when GM = 1
