8.4 Addressing Mode
The MC800 series MCU uses six addressing modes;
Register addressing
Immediate addressing
Direct page addressing
Absolute addressing
Indexed addressing
Register-indirect addressing
8.4.1 Register Addressing
Register addressing accesses the A, X, Y, C and PSW.
8.4.2 Immediate Addressing
→
#imm
In this mode, second byte (operand) is accessed as a data imme-
diately.
Example:
0435
ADC
#35H
When G-flag is 1, then RAM address is defined by 16-bit address
which is composed of 8-bit RAM paging register (RPR) and 8-bit
immediate data.
Example: G=1
E45535
LDM
35H,#55H
8.4.3 Direct Page Addressing
→
dp
In this mode, a address is specified within direct page.
Example; G=0

UART1 Transmit Shift Register
1. The register BITR and CKCTLR are located at same address. Address F2H is read as BITR, written to CKCTLR.
Caution) The registers of dark-shaded area can not be accessed by bit manipulation instruction such as "SET1, CLR1", but should be
accessed by register operation instruction such as "LDM dp,#imm".
2. The UART1 control register ASIMR1,ASISR1, BRGCR1,RXR1 and TXR1 are located at EE6H ~ EE9H address.
These address must be accessed(read and written) by absolute addressing manipulation instruction.
