2.11.4 Clock-asynchronous Serial I/O Mode (Compliant with the SIM Interface)
The SIM interface is used for connecting the microcomputer with a memory card I/C or the like; adding
some extra settings in UART2 clock-asynchronous serial I/O mode allows the user to effect this function.
Tables 2.11.8 and 2.11.9 show the specifications of clock-asynchronous serial I/O mode (compliant with
the SIM interface).

interface) (1)
Item
Specification
Transfer data format
• Transfer data 8-bit UART mode (bit 2 through bit 0 of address 037816 = “1012”)
• One stop bit (bit 4 of address 037816 = “0”)
• With the direct format chosen
Set parity to “even” (bit 5 and bit 6 of address 037816 = “1” and “1” respectively)
Set data logic to “direct” (bit 6 of address 037D16 = “0”).
Set transfer format to LSB (bit 7 of address 037C16 = “0”).
• With the inverse format chosen
Set parity to “odd” (bit 5 and bit 6 of address 037816 = “0” and “1” respectively)
Set data logic to “inverse” (bit 6 of address 037D16 = “1”)
Set transfer format to MSB (bit 7 of address 037C16 = “1”)
Transfer clock
• With the internal clock chosen (bit 3 of address 037816 = “0”) :
fi / 16 (n + 1) (Note 1) : fi=f1, f8, f32
• With an external clock chosen (bit 3 of address 037816 = “1”) :
fEXT / 16 (n+1) (Note 1) (Note 2)
Other settings
• The sleep mode select function is not available for UART2
• Set transmission interrupt factor to “transmission completed”
(bit 4 of address 037D16 = “1”)
Transmission start condition • To start transmission, the following requirements must be met:
- Transmit enable bit (bit 0 of address 037D16) = “1”
- Transmit buffer empty flag (bit 1 of address 037D16) = “0”
Reception start condition • To start reception, the following requirements must be met:
- Reception enable bit (bit 2 of address 037D16) = “1”
- Detection of a start bit
Interrupt request
• When transmitting
generation timing
When data transmission from the UART2 transfer register is completed
(bit 4 of address 037D16 = “1”)
• When receiving
When data transfer from the UART2 receive register to the UART2 receive
buffer register is completed
