This register is used for both Counter 0 and Counter 1. It is the LSB for both counters.

When writing to this register, an internal load register is loaded. Upon issuing a Load command through Base + 15, the selected counter’s LSB register will be loaded with this value.

When reading from this register, the LSB value of the most recent Latch command will be returned. The value returned is NOT the value written to this register.

This register is used for both Counter 0 and Counter 1. It is the MSB for counter 1 and the middle byte for counter 0.

When writing to this register, an internal load register is loaded. Upon issuing a Load command through Base + 15, the selected counter’s associated register will be loaded with this value. For counter 0, it is the middle byte. For counter 1, it is the MSB.

When reading from this register, the associated byte of the most recent Latch command will be returned. The value returned is NOT the value written to this register.

This register is used for Counter 0 only. Counter 0 is 24 bits wide, while Counter 1 is only 16 bits wide.

When writing to this register, an internal load register is loaded. Upon issuing a Load command through Base + 15 for Counter 0, the counter’s MSB register will be loaded with this value. When issuing a Load command for counter 1, this register is ignored.

When reading from this register, the MSB value of the most recent Latch command for counter 0 will be returned. The value returned is NOT the value written to this register.
