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.
