3.2
The following registers are related to the operating mode.
• Mode control register (MDCR)
• System control register (SYSCR)
3.2.1
MDCR is used to monitor the current operating mode of this LSI. MDCR should not be modified.
Notes: 1. Determined by the FWE and MD2 to MD0 pin settings.
3.2.2
SYSCR is used to select the interrupt control mode and the detected edge for NMI, select the
MRES input pin* enable or disable, and enables or disables on-chip RAM.

Description
Reserved
These bits are always read as undefined value and
cannot be modified.
Flash Programming Enable
Reflects the input level at the FWE pin. This bit
functions same as the FWE bit in the FLMCR1
register.
Mode Select 2 to 0
These bits indicate the input levels at pins MD2 to
MD0 (the current operating mode). Bits MDS2 to
MDS0 correspond to MD2 to MD0. MDS2 to MDS0
are read-only bits and they cannot be written to. The
mode pin (MD2 to MD0) input levels are latched into
these bits when MDCR is read.
These latches are canceled by a power-on reset, but
maintained at manual reset*
