5.2.9
Status register 0 (ST0) indicates the status of interrupts (TXINT and RXINT) and the
transmit/receive buffer. When any bit of this register is set to 1, an MPU interrupt request is
generated (if enabled).
This register is reset under either of the following conditions:
Hardware reset
Channel reset command
System stop mode
Notes:
Async
Byte sync
Bit sync HDLC
Read/Write
Initial value
MSCI Status Register 0 (ST0)
1. Reserved. These bits always read 0.
2. TRC14–TRC10 bits of TX ready control register 1 (TRC1)
3. TRC04–TRC00 bits of TX ready control register 0 (TRC0)
4. RRC4–RRC0 bits of RX ready control register (RRC)
5. In bit synchronous mode, RXRDY is set to 1 when data with EOM enters the
TXINT interrupt
0: No interrupt
1: Interruput
receive buffer.
