Section 30 SIM Card Module (SIM)
30.3.4
SCTSR is a shift register that transmits serial data.
The smart card interface transfers transmit data from the transmit data register (SCTDR) to
SCTSR, and then sends the data in order from the LSB or MSB to the SIM_TXD pin to perform
serial data transmission.
When data transmission of one byte is completed, transmit data is automatically transferred from
SCTDR to SCTSR, and transmission is initiated. When the TDRE flag in the serial status register
(SCSSR) is set to 1, no data is transferred from SCTDR to SCTSR.
Direct reading and writing of SCTSR from the CPU or DMAC is not possible.
30.3.5
SCTDR is an 8-bit readable/writable register that stores data for serial transmission.
When the smart card interface detects a vacancy in the transmit shift register (SCTSR), transmit
data written to SCTDR is transferred to SCTSR, and serial transmission is initiated. During
SCTSR serial data transmission, if the next transmit data is written to SCTDR, continuous serial
transmission is possible.
