y Flags: M1161 (8/16 bit mode switch)

Operands:

: Start device for source data

: Start device for storing the converted result

: Number of bits to be converted

Explanations:

1. 16-bit conversion mode: When M1161 = Off, the instruction is in 16-bit conversion mode. ASCII

codes of the 8 high bits and 8 low bits of the hex data in

S are converted into hex value and sent to

D (every 4 bits as a group). n = the number of bits converted into ASCII codes.

2. 8-bit conversion mode: When M1161 = On, the instruction is in 8-bit conversion mode. Every bit of

the hex data in

S are converted into ASCII codes and sent to the 8 low bits of D. n = the number of

converted bits. (All 8 high bits of

D = 0)

Program Example 1:

1. M1161 = Off: The 16-bit conversion mode

2. When X0 = On, convert the ASCII codes stored in the registers starting from D20 into hex value

and send the result (every 4 bits as a group) to registers starting from D10.

n = 4.
