8.5 SERIAL I/O
This microcomputer has a built-in serial I/O which can either transmit
or receive 8-bit data serially in the clock synchronous mode.
The serial I/O block diagram is shown in Figure 8.5.1. The synchro-
nous clock I/O pin (SCLK), and data output pin (SOUT) also function
as port P4, data input pin (SIN) also functions as port P20–P22.
Bit 3 of the serial I/O mode register (address 00EB16) selects whether
the synchronous clock is supplied internally or externally (from the
SCLK pin). When an internal clock is selected, bits 1 and 0 select
whether f(XIN) or f(XCIN) is divided by 8, 16, 32, or 64. To use the SIN
pin for serial I/O, set the corresponding bit of the port P2 direction
register (address 00C516) to “0.”
Fig. 8.5.1 Serial I/O Block Diagram
The operation of the serial I/O is described below. The operation of
the serial I/O differs depending on the clock source; external clock or
internal clock.
