CHAPTER 15 SERIAL INTERFACE UART2

s Manual U14260EJ3V1UD

(6) Transfer mode specification register 2 (TRMC2)

This 8-bit register is used to specify the transfer mode, switch the interrupt source of INTST2, enable or disable

occurrence of the receive completion interrupt in the multi-processor transfer mode, and specify the multi-

processor transfer appended bit.

TRMC2 is set by a 1-bit or 8-bit memory manipulation instruction.

RESET input sets TRMC2 to 02H.

Before rewriting TRM12 and TRM02, clear bits 6 (TXE2) and 5 (RXE2) of asynchronous serial interface

mode register 2 (ASIM2) to 0.

Before setting a value to MPS2, confirm that bit 1 (TXBF) of asynchronous serial interface transmit

status register 2 (ASIF2) is cleared to 0. Before writing transmit data to transmit buffer register 2

(TXB2), specify whether

The setting of bits 0 to 4 (ISEM2, SL2, CL2, PS20, and PS21) of ASIM2 is valid in all the transfer modes.

The specification by MPIEN2 and MPS2 is valid only when bit 7 (TRM12) is cleared to 0 and bit 6

(TRM02) is set to 1 (i.e., when the multi-processor transfer mode is set).
