PERIPHERAL FUNCTION EXTENSION REGISTER
The serial I/O transfer direction can be switched by setting the bit
0 in the peripheral function expansion register to “1”. This function
is valid only when the bit 6 in the serial I/O control register is set to
“1” (when the clock synchronous serial I/O is selected). P47 can
be selected as the output pin of the clock synchronous serial I/O
by setting the bit 1 in the peripheral function expansion register to
“1”. When setting P47 to the SOUT pin, set the bit 7 in the port P4
direction register to “1”. This function is valid only when the bit 6 in
the serial I/O control register to “1” (when the clock synchronous
serial I/O is selected). P-channel output of TXD and SOUT can be
disabled by the bits 2 and 3 in the peripheral function expansion
register. Set the bit 4 in the UART control register to “1” after se-
lecting the pin to disable the P-channel output. XCIN frequency
signal can be output from the port P41 by setting the bit 4 in the
peripheral function expansion register to “1”. Set the bit 0 in the φ
output control register and the bit 1 in the port P4 direction regis-
ter to “1” to output the XCIN frequency signal.
