15.3 Registers Controlling Serial Interface CSI10
(1) Serial operation mode register 10 (CSIM10)
334
Address: FF80H After reset: 00H R/W
CSIM10
Serial interface CSI10 is controlled by the following four registers.
Notes 1.
Caution Be sure to clear bit 5 to 0.
Symbol
CSIM10 is used to select the operation mode and enable or disable operation.
CSIM10 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.

TRMD10
DIR10
Bit 0 is a read-only bit.
To use P10/SCK10/T
(00H).
Bit 0 (CSOT10) of CSIM10 and serial I/O shift register 10 (SIO10) are reset.
Do not rewrite TRMD10 when CSOT10 = 1 (during serial communication).
The SO10 output (see (a) in Figure 15-1) is fixed to the low level when TRMD10 is 0. Reception is
started when data is read from SIO10.
Do not rewrite DIR10 when CSOT10 = 1 (during serial communication).
