IA186ES/IA188ES
8-Bit/16-Bit Microcontrollers
Table 19. Processor Release Level Register
5.1.4
The AUXiliary CONfiguration Register configures the flow control signals for the asynchronous
serial ports. AUXCON controls data bus width (8- or 16-bit) for lower memory, middle
memory, and IO accesses and contains 0000h at reset (see Table 20).

Bits [15–8]—PRL [7–0] → The latest Processor Release Level.
Bits [7–0]—Reserved.
Bit [15–7]—Reserved.
Bit [6]—ENRX1 → When set to 1, the cts1_n/enrx1_n pin functions as cts1_n. When 0,
it functions as enrx1_n.
Bit [5]—RTS1 → When set to 1, the rtr1_n/rts1_n pin functions as rts1_n. When 0, it
functions as rtr1_n.
Bit [4]—ENRX0 → When set to 1, the cts0_n/enrx0_n pin functions as cts0_n. When 0,
it functions as enrx0_n.
Bit [3]—RTS0 → When set to 1, the rtr0_n/rts0_n pin functions as rts0_n. When 0, it
functions as rtr0_n.
Bit [2]—LSIZ (IA186ES only) → When set to 1, 8-bit data accesses are performed in
lower chip-select (lcs_n) space. When 0, 16-bit data accesses are performed.
