18.5.4
If the TEIE bit is always set to 1 during continuous transmission, unnecessary transmit end
interrupts (SIMTEI) occur because the TEND bit is set to 1 every time transmission is completed.
To avoid unnecessary SIMTEI requests, the TEIE bit in SISCR should be set to 1 only after the
last transmit data is written to SITDR and SITSR starts transmission.
Figure 18.10 shows the signal waveforms when TEIE is set to 1.
18.5.5
When switching between the smart card interface mode and standby mode, in order to maintain
the clock duty, the following switching procedure should be used. Figure 18.11 shows standby
mode switching procedure. (1) to (7) in figure 18.11 correspond to items 1 to 7 described below.
• When changing from smart card interface mode to standby mode:
SIMTEI
request
TEND
TDRE
TEIE
1. Write 0 to the TE and RE bits in SISCR, to stop transmission and reception operations. At
2. Write 0 to the CKE0 bit in SISCR to stop the clock.
3. Wait for one clock cycle of the serial clock. During this interval, the duty is maintained,
4. Make the transition to standby mode.
the same time, set the CKE1 bit to the value for the output-fixed state in standby mode.
and the clock output is fixed at the specified level.
