Fig. 8 Serial I/O block diagram
SERIAL I/O
M37210M3-XXXSP has a serial I/O.
A block diagram of the serial I/O is shown in Figure 8.
Synchronous input/output clock (SCLK), and the serial I/O pins (SOUT,
SIN) are used as port P4. The serial I/O mode registers (address
00DC16) are 8-bit registers. Bits 0, 1 and 2 of these registers are
used to select a synchronous clock source.
Bit 3 decides whether parts of P4 will be used as a serial I/O or not.
To use P42 as a serial input, set the directional register bit which cor-
responds to P42 to “0”. For more information on the directional regis-
ter, refer to the I/O pin section.
The serial I/O function is discussed below. The function of the serial
I/O differs depending on the clock source ; external clock or internal
clock.
