14.1.2 Switching modes between CSI1 and UART0
at the same time. Select CSI1 or UART0 in advance by using port mode control register 3 (PMC3) and port function
control register 3 (PFC3) (refer to 4.3.3 Port 3).
14.2 Configuration
read from the SIOn register.
334
CSI1 and UART0 of the V850ES/SA2 and V850ES/SA3 share pins, and therefore these interfaces cannot be used
Caution CSI1 or UART0 transmission/reception operations are not guaranteed if the mode is changed
Remarks 1. n = 0, 1
CSIn is controlled by the clocked serial interface mode register (CSIMn). Transmit/receive data can be written to or
(1) Clocked serial interface mode register n (CSIMn)
(2) Clocked serial interface clock selection register n (CSICn)
(3) Serial I/O shift register n (SIOn)
The CSIMn register is an 8-bit register for specifying the operation of CSIn.
The CSICn register is an 8-bit register for controlling the transmit operation of CSIn.
The SIOn register is an 8-bit register for converting between serial data and parallel data. SIOn is used for
both transmission and reception.
Data is shifted in (reception) or shifted out (transmission) beginning at either the MSB side or the LSB side.
Actual transmit/receive operations are controlled by reading or writing SIOn.
2. × = Don’t care
during transmission or reception. Be sure to disable the operation of the unit that is not used.
