Section 20 Serial IO (SIOF)
20.3.9 Transmit or Receive Timing
Figures 20.13 to 20.19 show examples of serial transmit or receive of SIOF.
(1) A Case of 8 bits Monaural (No.1)
Sync pulse method, falling edge sampling, transmit data and receive data are assigned to slot No.
0, frame length is 8 bits.
1 frame
SCK_SIO
SIOFSYN
TXD_SIO
RXD_SIO
Lch. DATA
Slot No.0
1 bit delay
Setting: TRMD = 00 or 10, REDG = 0,
FL = 0000 (frame length 16 bits),
TDLE = 1,
TDLA3 to TDLA0 = 0000, TDRE = 0, TDRA3 to TDRA0 = 0000,
RDLE = 1,
RDLA3 to RDLA0 = 0000, RDRE = 0, RDRA3 to RDRA0 = 0000,
CD0E = 1,
CD0A3 to CD0A0 = 0000, CD1E = 0, CD1A3 to CD1A0 = 0000
